help! prewar schwinn?

[bon]

hi guys! i'm new to this incredible site and i wish someone might now what year and model of this schwinn bike that i recently bought.. only the frame and the tank are salvageable.. all i know is it is a prewar bike. thanks if you could shed some light on this one.
serial has GY 10 on top of 11160, on the side it has a logo with number 4100.

This one has me stumped. The tank and head tube/top tube welds look exactly like a Schwinn. The drop outs and the serial number don't look like any Schwinn I've seen. With drop outs having ears like that, you'd think this frame would have a straight down tube.
I hope someone can figure this one out. That's about a $200 tank, by the way. Gary

Maybe the GY is Goodyear? This is a pic of a 1938 Goodyear bike, made by Colson. The dropouts look like yours. I also noticed the welds on the headtube, they aren't smooth like a Schwinn. Maybe a Colson?

It rally doesn't look like a Schwinn to me. The tank obviously is, but maybe it's a prewar roadmaster or western flyer that a schwinn tank just happened to fit well.

when we bought it, i was really thinkin schwinn, but then when i stripped it, i got a little messed up. the rear looks like the colson in the picture that Wildcat posted. maybe someone decades ago did this to this bike and its amazing he was able to put the schwinn tank to fit in. and he did a nice h*** of a job.
