prewar Schwinn Serial

Big bowl of serial

I guess my question has alway been what exact time periods or when exactly did Schwinn change the serial stamping. Obviously not December 31 of each year. I have a very early example of a 1935 double diamond cycle plane frame that is "big fancy" A something or other and also has a side stamped 6 35 on the bottom crank housing. I got this frame from a very "nice some of the time" knowledgable gentleman who figured that was the production date which I would agree after examining it. Same stamp font for both number patterns. So maybe someone can start crunching numbers from production year charts by using that date and see where they end up in 1942 or 46. So when exactly did they go from big fancy to small tight and uniform to normal standard serials??

According to This article, the serial numbers got tighter in 1937.

Yes they did

Yes thanks! I think I established that as have others, but when exactly in 37??

Oops!

I see some other incorrect data on that link as well with the characteristics.

Lug at seat stay?

Hi, did anyone notice the lug at the seat stays and the top tube? Also the the rear fender support at the seat stays is straight across? My 39 is shaped to the fender, is this common on the 40?

Crank Arm Date

37Fleetwood, did you find a date on the crank arm on your bike?
Since there was discussion on the transition of the letter E to F in 1940, a pic of the crank arm from the Brown DX in this thread, This is unlike other date stamps I have seen, A.S. & CO one side, 40 with "E" prefix other side.
It would be interesting to know if there is a crank stamp "F" prefixing 40 out there somewhere, or "E" prefixing 41.

my crank came with the fender set I bought on ebay. I think this came up earlier in the thread. in any case it's an undated ladies crank.it has the 502, or 512 or whatever if I remember correctly.

I forgot to mention, for April Fools Day I took the DX out for a ride at the Cyclone Coaster ride. I re-badged it as a Huffy and got several people. I was told a few times by some of the guys that they never knew Huffy made a bike that looked like a DX. it also shocked a few to see me on a Schwinn. the bike rode terrible and almost killed me. I think it was the tires, but it was fun poking at everyone and they got a laugh out of it too. still a long way to go on this one.

just a quick update!I just bought 3 or 4 more DX bikes. I only intend to keep one but they came up in the wrong order and I seemed to keep buying them. the 4th one is still being considered, it's a girls around 1940 or so.
as soon as I get them, I'll post photos and serials so they can be added to the dating debate.
I bought a boys B.F. Goodrich, which is the one I'll keep, the rest are going to go if anyone is interested in parts. none of them but the B.F.G. are original bikes, so don't feel bad about them getting parted out.
