Schwinn B9/B10’s

[RustyHornet]

Not finding a whole lot of these around. Picked this up at Memory Lane in a trade deal. I know there are a lot of wrong parts, but overall it’s a good start for what I wanted. Would like to see some more!

Upon first research it appears it’s a 1934 model B9. I don’t think the head badge is original based on the small hole above this one, perhaps it should have a brass Planes and Trains? Still learning on those. The fork is an old Wald replacement. I’ve not seen one of these big clover sprockets yet, but I like it. Looks like it was a dark green color.

Post yours please! Need some ideas and information!

I think the planes & trains badge dates to the late '40s.

Perhaps this one does, but I do not believe it to be original to the bike. There is a brass planes and trains that was prewar.

Digging into this one a little bit. Reading more and more, learning about these years and models. I have read that these bikes all originally came without chain guards and had a straight crank. This one has a dog leg, which looks like it might be a 1933? Still looking like the serial puts the frame as a 1934 build. The Morrow is dated 1940, so wheels have most likely been replaced.

I‘d love to find an original truss fork, original style handlebars with cross bar. I have an original style stem. Would also love to find an original straight crank, this dog leg is bent and threads stripped out of the pedals.

I’d also love to find another US Royal Nobby tire to match this one!!!

Looks like an earlier, 28-er frame I think. Not sure any parts are original

I'm with @SKPC.... 26" wheels look small in that frame. Been doing research trying to nail down some info on my '27 moto and it hasn't been easy.... I did come across a chart in a thread somewhere (can't seem to find now) which puts your serial at '33. If spring of '33 was when the ballon tire 26" was first introduced than maybe yours is from the first half of the year? The 33 on the crank seems like a coincidence... doesn't look like a Schwinn crank.

I don’t believe any of the parts are original either. And I had those same thoughts on the frame!

I agree the wheels look small in it and had those same thoughts. So I measured the length of the rear triangle and it measured the same as my ‘39. I don’t have a 28” bike to compare it to right now. My first thoughts were the crank isn’t a schwinn, but my ‘39 crank is “stamped” similar to this one, no AS&Co just a 39.

I also came across that same chart, but kept reading and it seems that it has been disproved. I had come across another site that seemed to have more correct info and that’s where I’m getting the ‘34 from at this moment. I’d love to nail this one down for sure!

Perhaps you can take some pictures of your fame, and some measurements and we can compare!

Here’s some comparison pics. If there is a for sure way to tell if a frame is a 28 or 26, I have not come across it.

Red bike is my ‘39

Last pic shows where I was hooking the tape.

I guess the biggest question is, what did the manufacturers change when they went to 26”?
