The following excerp may help to clarify the clay issue, and also raises other questions.
In 1987, Phil Egan was not only working on Design and Destiny, but he was preparing a biography for Automobile Quarterly on his friend Alex Tremulis. In a December 1987 reply on the draft, Tremulis corrected Egan on the sequence of events as he remembered them in relation to the Tin Goose, the clay models, and the Lippincott team.

So it seems entirely plausible that the Tin Goose, at least in part (maybe not 95%), predates the clay models, and that's why Tremulis' story of going straight to metal without the benefit of clay may, in part, be accurate.
As far as I could gather, Preston Tucker told Tremulis to take a "vacation" in March of 1947 at which point the Lippincott team came in on March 4, 1947. However, I thought he was only out for 1 month (not 3 months) during which time he was kept apprised of the goings-on by insiders at the plant.
Trying to find the facts is a bit like trying to determine the truth in Rashomon. Somewhere in the middle is most likely...
I just found this reference last night, so I thought I'd put this one up for the experts (you all).
Does anyone have any records for the dates on which the Tin Goose was started and the stages of development?
Any photos or dates of the Tin Goose in the process of being built?
How about records/memos for the purchase date of the clay?
There must be records for the million dollar rear end tooling. Anyone have some?
Anything related in the Dan Leabu memos that turn up on eBay?
