John, I’ve found no direct links to the 1935 Harris FWD Streamlined Speciale so far, but a few interesting tidbits:
As far as Alex Tremulis’ early influences and the possible exposure to the Harris Speciale, here’s a letter he wrote to Gordon Buehrig on October 15, 1975 in which he references Buehrig’s guided tour through his 1935 design studio. It’s conceivable that there may have been something on your Harris Speciale in Buehrig’s studio at that point (also note how Tremulis points out the politics involved with the auto industry – some things never change…). Certainly when Tremulis was made Chief Stylist at Auburn-Cord-Duesenberg in 1936 he had access to all the A-C-D dreamworks.

As part of the Chrysler Newport/Thunderbolt article that was published in 1975 Special Interest Autos, Tremulis goes into much greater detail on the designers of the day. This account was edited out because it was considered non-sequitur to the Newport story, but offers more insight into the stylist’s world of that era. I’ve thrown in some pix of some of the referenced cars. It’s pretty clear that the 25 year old Tremulis was well aware of the aerodynamic designs that were going around in the 1920’s and 1930’s as well as the stylists that were credited with the designs. Here’s Tremulis’ unedited introduction to the Newport/Thunderbolt story of the time while he was at Briggs:
What a violent transition it must have been for, as an example, Edsel Ford to leave the River Rouge Dearborn area where executives like Ernest Kanzler and Fred Rockelman were committing political suicide trying to convince the senior Henry Ford that the models T and A were visions of the past, best looked at through a rear view mirror and that a sleeping giant was emerging on the horizon called General Motors who was putting all their eggs in one big basket called the Art and Colour Section headed by Harley Earl. Here they could express their philosophies and, on occasion, we stylists would be assigned to them to work out some of their creative ideas.
On several occasions I was privileged to work on Edsel Ford’s concepts. I remember one particular design that Mr. Ford called the New Era. After some 35 years his design has certainly survived the acid test of time. He had insisted on the first of the thin roofs and a curved glass windshield that radiused into the windshield header which was to have the thinnest windshield pillar ever. And get this: a horizontal crease line on the door which was to generate two planes of light with the reflected plane creating an illusion of light which was to exaggerate the length of the car. He demonstrated this facet by folding a sheet of cardboard and then by lighting a match demonstrating the light and shadow qualities thusly expressing his design philosophy most eloquently. I recall one of my colleagues exclaiming; “Where in hell did Mr. Ford get that match?!?” as in that frame of time smoking at the Ford Motor Company was strictly forbidden. Smoking in the inner sanctum of the men’s washroom was a calculated risk. Those suspect behind the closed doors were simply drenched with a bucket of water which descended upon the sitting offender with the fury of a roaring Niagara. Then the doors were literally pulled off the hinges and the offenders badge was ripped off by one or two of the secret police, who numbered some eight or nine hundred men and who also masqueraded as workers at the Ford Motor Company. This act, the removal of the badge, equaled the finality of the ripping off of an officer’s epaulettes in a military court martial. I recently read of an automotive buff who was the proud possessor of a company badge that bore the name of Henry Ford II. I have often wondered how in hell Henry the II ever managed to get back into the Ford Motor Company and eventually take over the reigns of the company that was rightfully his without that badge. Getting back to Edsel Ford. Mr. Ford also insisted that the car need be no higher than 50 inches, about a foot and a half lower than existing motor cars of that time, since the sins of the drive shaft were now eliminated by the rear engine placement. As to the front fender height Mr. Ford expressed a desire to make the hood, if possible, actually lower than the fenders themselves. Mr. Ford was a man of great design sensitivity, tremendously inspiring and he could actually sketch. He would pick up sweeps and would say “let’s try this one and see what happens”. As to his enthusiasm for rear engine philosophy he had been brainwashed by John Tjaarda as early as 1933 when he displayed the rear-engined Ford Briggs Body Special at the 1933 Chicago Worlds Fair.

This exciting concept was the Tjaarda brainwashing technique that eventually inspired the Lincoln Zephyrs, the first truly aerodynamic cars that boasted of a lower coefficient of drag than the legendary Chrysler Airflows which introduced the philosophy of streamlining to this country.

Edsel Ford believed in low, streamlined cars. I remember an incident that occurred in the early 50’s when Gil Spear, chief stylist, was presenting a very low 48 inch high sedan called the Diplomat. About 30 of us in styling were at its unveiling and most everyone was wondering what Henry Ford II was going to say after he banged his head on the roof getting his 6 foot frame into the car. I remember saying “Don’t worry, he’s an Edsel. He’ll get in like an old pro.” He got in with the grace of a ballerina. I doubt if the legendary Sterling Moss, notorious for his flying entrance LeMans starts in a Cisitalia coupe could have ever beaten Henry II’s time in getting in and out of super low cars. We applauded his performance that day with enthusiasm for a styling victory. Now maybe we’ll get the go signal for some new exciting low cars. Not so with K. T. Keller of Chrysler whose cars always seemed to have the steering wheel a bit out of reach and while offering excellent entrance qualities always seemed to penalize the Chrysler stylists with a shorter hood length of 2 or 3 inches. Years later, when the legendary Virgil Exner designed the first of an illustrious line of dream cars, he dubbed his creation the K-310, not in tribute to the car’s alleged HP, but K. T. Keller’s vital statistic which was measured in poundage.

John, you may want to research more of the LSR attempts of the 1920’s and 30’s, since design elements of these cars show up in one-offs of the era. The Harris Speciale looks a lot more like a miniature version of Campbell’s Bluebirds:

It’s possible that they were all exposed to the Harris Special if its design had ever been in the Auburn-Cord-Duesenberg facilities. Tremulis assisted Derham and Newport with their car. Although their fabric-based body doesn’t look much like the Harris Special, 6 or 7 years later Tremulis sketched his version of an Aeronaut which does have some design similarities to both the Chrysler Thunderbolt and the Harris Special. Whether or not it was just reuse of the Aeronaut name or if it was part of a bigger project, I’m not sure at this point, but here’s the Tremulis rendering of a retractable drop-top bubble-top rear-engined Aeronaut, about 1943:

And here’s the Derham-Newport fabric-skinned 1935 Aeronaut:

From another great site
http://www.coachbuilt.com/ :
In the Feb-Mar 1973 issue of Special Interest Auto (#15), Newport reflected on the Aeronaut project:
"Just before Phil left Duesenberg, we got to working on this Ford idea of building a light, fast V-8 chassis with a fabric body on it. We built it sort of like an airplane and made arrangements with the former Weymann Body Co., at that time managed by A.H. Walker, to make the bodies for us. We chose Walker for two reasons - he was familiar with fabric body construction, and the old Weymann plant in Indianapolis was very handy.
"But the bodies we built didn't use real Weymann flexible construction. Rather, our bodies used a solid wooden frame covered with wood strip paneling, like boat-strip planking-each strip being about 3/8 inch thick and half an inch wide to get the shape. When that was all sanded and smooth, we covered it with cotton padding and finally covered that with airplane linen. The linen was then painted with the same paint as the metal fenders, hood, etc., and you couldn't tell it was fabric unless you actually touched it.
"We built two different styles of cars. The first, based on the 1934 Ford, was immediately outdated when the 1935 Fords came out, so we had to make another car based on the '35 Ford. We built two of the 1935 model. The fellow who put up the money to build these cars was Harry S. Liebhart from Denver.”
Alex Tremulis was also involved in the project and in the Apr-May 1973 issue of Special Interest Auto (#16), he told of his experience with the short-lived Derham project:
“The Weymann principle saved us 611 pounds and was very quiet. Bert Walker, founder of Weymann, used to tell me that fabric construction was cooler in summer and warmer in winter. I worked for Phil Derham in Indy for about three months. My job was to take cost-outs of the Aeronaut, which was to sell for $3,250. I recall designing around the 1935 Plymouth front end, too, to a price of $2,750. It looked like an order of 50 cars.
“We had at least 10 Aeronauts on the production line, I remember. We used to dope them daily with about 15 coats to shrink and stretch them. When painted, they were just like metal. For a while, an Aeronaut was being considered as a pace car for the Indy 500. Unfortunately Harry Liebhart, our angel, was bringing the one finished car back from Denver and sideswiped a taxicab just three blocks from the plant. He paid for it, cut off our financing, disappeared for two months, and the venture collapsed.
“Herb and Phil had done a magnificent job on this car’s styling and it had fantastic performance. I really think that there were three cars completed and maybe 10 bodies in various stages of construction. If we had paced the Indy 500, it would have meant success, as we had many interested prospects. It was a very low budget operation. I think I was being paid $35 a week, but the experience was fabulous.”
