tatra 77 and 77a

I mean that here are the blueprints of two rather strange and interisting cars, at least in my opinion. I happen to have the specifications for both of the cars pictured. I can post the specifications if someone here is interested in the technical data.

I guess hes saying here are two wierd cars if anyone wants to do them I also have complete specs for them as well. Great donation. Seems Tatra is the car of the week here or something.

Tech. spec.???
:p Of course I am interested!
ANY pre-war car's specification is welcome.
If it's not too much work for you, I'd be happy if you could post data here.


Thank you

PS: Nice homepage you got. Must be so much work to make High-Poly cars... I reach the limits of my abilities already at 15,000 or so. Great work on the Cord!

Fabian :)
