Troy,
I think it was the latter, because I honestly can't invision the company researchers being TOO type specific! To them, it's; "A Huey's a Huey's a Huey, and the kids that build models won't know the difference anyhow."
The Bench Seat material sounds like it will be just the thing... are you going to make the "seat back" from the same material?
The transition period between "B" & "C" model Huey's seemed to be a vauge one, particularly in physical appearance; Some of them, which otherwise appear to be "B" Models, have the "Pitot Tube" mounted atop the cabin.... some "C" Models have the small (B Model) engine intakes... I think the model builder should pick out a particular example and call it whatever the real thing was called... at least they'll have photographic/description validation of their build's aithenticity.
I stopped building "Generic" models a long time ago.
BTW: Guess what I'm currently working on? A 1971 Chevy Monte Carlo, fixing it up like Bobby Allison's "Coke Machine".
Been waiting 32 years for an accurate set of decals for that car, finally located some, so it's getting 110% of my attention at the moment.
