I agree Falcon's can vary in quality like any other brand. I have a 60's two 70's and beleive my last one is early 80's. But they are are 531 reynolds some single tubed and others double butted. The 80's is full campy equiped. I do have a few catalogs for reference inclusing a parts cat. I like the older metal badged versions.
From my small Falcon collection experince has shown:
531 Reynolds Single butted were usually 26.0 and the later double butted 27.2. Though most of my Falcons are a bit older that seemed to be the standard.
