It's not that straightforward, I'm afraid. Dan Gurney doesn't accept the 'T1G' designation, which was given to it by its designer Len Terry. In this very ancient thread:
A letter from Dan Gurney
although the letter itself is no longer available, the relevant quote from it is:
There's further clarification from Doug Nye later on in that thread:
I'll stand my ground. When you do some research on cars you don't find the words "sharknose" or any other like that. Those are nicknames. For the Eagle cars, I've found it both ways, in very good sites and in crappy ones. I accept that all this can lead to confussion and/or discussion and I like that. And by the way, I'm no kid, I'm pushing 46 and got no time to glue my pants to my computer's seat and spend all day doing "research". And keeping with the subject, ¿how you name the Lotuses, by the number alone or with a Mk before that number? I've found it both ways. ¿The Brabham cars were raced by Motor Racing Developments or by Brabham Racing Organization? I've found it both ways. ¿The BRMs were raced by Owen Racing Organization or by the Team BRM? I've found it both ways. May be the veterans know better. I'll leave now, got to drink my milk from my bottle.
