Frame ID?

I recently purchased this frame from another member but I am not sure it's even a Schwinn frame. Any thoughts on what it could be? Thanks

If it was brazed I would swear it's a b6 frame....

I say it is a Schwinn frame. The serial comes up the first of Jan, 1952 and no other maker used a stamped rear dropout like that. Why do you say it's not brazed? Chain guard mount on the BB may have been replaced at some point.

Imo. ... something is fishy with welds and especially the connection points on the head tube. What's up with the dual serial number? The front mount for the chain guard is way wrong... and if replaced. ..
how would it have broke off? and wouldn't it have still been attached to the guard after it had? So wouldn't you just use the piece that broke originally?...

This is not a schwinn frame.... too much wrong.... I say reissue or 80s something.?... Axxxxx serial number on BB.?..yet frame takes big schwinn badge?... the tips of the drop outs are too squared off and narrow... and the serial is all squiggly. .. and the welds look like crap....

The gas holes in mine are usually not nice little drilled holes either. .. actually the whole part where the electroforge took place is honestly really clean!. usually Slag is hanging everywhere on that inside joint.... here is the drop out... it looks off.. especially the bottom .. and honesty in the pic, that metal looks too thick to me... but It may juat be the pic.

Down tube has a weird bend in it.

My bad, type error. Meant 52, which some 52's still had the numbers on the BB. So that's a 46 then. As far as the guard mount, I purchased a 1961 frame with a busted off guard tab on the bottom bracket. And it wasn't on the guard when I purchased the bike from the original owner. They were just brazed on flat stock until 1962. Cleaning up the slag before that frame was primed would be no big deal. People are still doing it today before they do a repaint. Lots of little idiosyncrasies on that frame and if it's a fake, someone sure spent a lot of wasted time doing it. I'd strip it down and take a closer look at the welds etc. I've seen crappy joints on other Schwinn frames so I didn't even consider that. And if it's a Whizzer frame would they be somewhat different than the run of the mill frames? Stripping it down may also show if the frame joints have been repaired or beefed up, like the cantilever/down tube welds. I'm still thinking that's a Schwinn frame that had some personal loving by someone.
