It's pretty much, mainly a frame. On the side: Waz-sup-wit-dat color? Ebay photo has it, I have a 41 girl CWC Western Flyer and yours too. Must have been like, an over stock paint sales in the 50-60's.
Anyway, the wheels, front is probably from a CWC the rear maybe a Huffy or Murrey drop center or, because that Bendix is wrong for year and I expect the rim is from another manufacture potentially from the 60's.
Seat I guess U no already, fenders, chain guard handlebar don't belong. The goose neck, (Stem) can't say for sure but looks like a late 40-50's Wald that is found on Schwinn occasionally and CWC . Pedals appear to be 60's. Kind of thinking the chain wheel and crank may not be pre-war.. Fork is not period either and IDK for sure for the size but, the fork could be a post war Schwinn or CWC.
So, if you intend to restore this frame, ya got quite a task. And yeah, that weld on seat post is strange. The color looks like it may be lead but not all Schwinn have lead to make em smooth. Yet, very strange B/C it looks like it was molten and squished on for the oozing up like it is. . Probably just grind that down unless it's cracked.
As far as the model goes, at this stage, it can be any model you chose it to be. Moreover, get her to ride, and getty-up!
