I wouldn't take this list as the gospel. My B10E has a serial of 15778 and the '40 BFG I just bought has a serial of E95177 and the original Morrow dated hub puts it at 4th Qtr 1940. The bike may have been sold as a '41 model though? V/r Shawn

V/r Shawn, trying to identify this B1 what year do you consider yours. Can not pull the crank, not a dog leg looks like a new Schwinn crank.

Strange, the last two digits were double struck, and it has a leading #1 verses the letter. I'm going to presume this is tween piece, somewhere between 1934 and 1935. It doesn't have the 6 digits and it doesn't have a preceding letter. Schwinn may have started out their new serials in 1935 with just 5 digits and soon after dropped that number 1 and replaced it with a letter and 4 numbers. Hopefully someone can verify or dispute this theory.
