I was looking at this earlier. I'm definitely stumped.
It does have a lot of Westfield details; i think that's a good bet; I'm wondering if it's a gender-bender with 2 donor bikes? Just a wild, outta left field guess. Regardless, it looks very cool. Does the construction seem to be the same throughout, or are the joints at the seat-tube a bit different?
Just some good ideas for IDing these old bikes: lots of pics; at least one good whole bike from the drive-side, and then plenty of close-up detail shots of the dropouts, the headtube junctions, the fork crown, truss-rod set-up, the seat cluster, the BB junction, etc. The headbadge area is a huge help too, even if the badge is gone. These details really offer a lot of clues as to who made the frame, then we can try to dig deeper and find a year, what the Badge was (many times, different from the maker), and how it may've been originally equipped. Bolt-on items don't offer a whole lot of help (eg, crank, sprocket, stem, bars, wheels, fenders) unless you can be reasonably sure that the bike is mostly original. After 70 to 80 years, it's tough to be sure on that...
