The GP35 had two different style of frame construction. The early ones
(phase I) had a frame like a GP7/9/18, the later ones had a frame that
was the same construction that is still used today ( an early GP35 can
be noted by the airline running outside the airtank above the fuel tank
and by a thicker side sill when compared to a 38/40 especially above
the fuel tank). If you want further info on the actual differences in frame
construction I'll have to dig into the archives. I don't believe their were
any differences in the SD35 frames throughout it's manufacturing span.

As far as drawings go, from the ongoing discussion in rec.models.rr,
I gather there isn't really anything out there. There was a old carstens
book that had a drawing of a SD35 but no one could remember whether
it was any good or not. They DID remember that some of the Alco
drawings in the book were terrible however...
