Curious about CWC in the 40's, 'how many bikes built in 1940?', I stumbled on a bit of data so, I stole it (Screenshot) to put here: Dr Tomas D Mueller, son of The Vice president of CWC; Homer L. Mueller. Citing that, in 1940, Homer would brag of having 50 different head badges on his desk ("Place cards") for all the different makes and models they produced. And that in 1940,the whole bicycle market was split 3 ways: Schwinn, CWC and the rest. Finally an end to when CWC croaked off into AMF: 1953. And a few more tid-bit factoids. 'Popular Mechanics' Aug 1996.

I am glad I found this thread I had no idea who made my bike until now. I'm not sure if the springer forks, crank and chain gaurd are original? Looks like there is a similar fork on what I believe is a CW made firestone bike so maybe its original?
Any clues to what what I have and approximate year (47is?)would be appreciated. It's a cool bike and I can't wait to ride it.

"A" serial number, no "CW" marking, curved fender struts, bladed fork and winged H badge.

Any ideas?

This recently popped up from I don't know where but, this later 1948 with a CWC and numbers above 48-51 doesn't seem right because nobody's found 48-51 numbers following the Cw mark wit 48-51. 52-55 yes but, otherwise no go. yet, the earlier 47 and below does.

this would mean, IF IT'S CORRCT THEN, yours would be; Dec 46- Feb 1947. . And the way yours appears, given all the data in this thread; it's pretty close too.

Think yours would be an 46-47 but the chart I just posted above doesn't confirm that. In fact it doesn't have a G with Cw mark , but. it's no different than the bike posted above, prior to yours too. Except it's a girls bike but the drop out looks identical. So, wild guess is it's 47 and that chart doesn't know it all. Potentially, the Cw stamp began in 47 verses 48. And for the front sprocket [chain ring] it's a Roadmaster, [see article above your post] CWC's own brand.

Thanks. But now it's a 2017 custom 6 bar. :)

I think I've posted this earlier but Phil is very knowledgeable on CWC dating.....
The key to dating your bike is the Cw symbol stamped after the end of the serial number. CWC ran through the same serial numbers several times from 1935 through 1956 and for postwar bikes the key to dating them is to first recognize the features that define them as postwar frames and then look for the symbol that follows the serial number. Bikes with the Cw stamp were from the second postwar run through the alphabet and the first bikes in this series rarely have the Cw stamp. By the time “D” was reached the suffix stamp became quite commonplace, probably to begin separating the series from the first wartime or postwar “D” serialed bikes. My best data-modeled estimate is that the Cw series was produced from 1947 through 1949. The exact transition from the first series to the second series is still debatable so I have slid the scale a bit several times to try to align it with actual bikes, ads, and other factors to come up with the most likely scenario. The second postwar serial number series bikes were produced with serial numbers ranging from A00001 through J99999, assumedly in sequence. A bike with a “D” serial number would, following this logic, have a build date in approximately mid 1948.

That chart above, has the dates of C series and if the D series was started on the date it says the next series placement would be that D series Started August 1947.

That line goes on too. Saying the run ended in September. Yet it is followed with the year 1952. The periods of the other, prior runs are about the same length. I think it possible September is the line you're looking for; 'The transition from the first series to the second'.

[edit] No, not Sept. exactly, the transition in the D Series would be during Aug. through Sept. 1947. chop that in half, then, September is your sugar daddy.

Picked this up an antique mall. I had no clue what it was but thought it looked pretty cool. The vendor said it was a 50s era Schwinn. I've owned Schwinn's most of my life and knew it wasn't. I discovered through the CABE that it was indeed a CWC. I'm still not sure of the year. 1940?

Nice pictures! I see now what they mean when they say the earlier drop-outs were bead welded instead of spot welded.

Not the prettiest welds back there so kind of surprised since most of the frame joints are smoothed out. Frame feels rock solid. Wonder how carbon fiber will hold up 80 years from now?

I just picked this up from another CABE member. So perhaps it has appeared in this thread before, but I couldn't find it if is. The seller said he thought it was a 1947 or there about....
The serial number gets fainter as the numbering progresses, like maybe the person stamping the numbers was running out of steam as he progressed with the duty, but the number appears to be A38080 with the CW very very faint. Almost lost. It must have been about quiting time...LOL...
I plan to repaint it as up close and personal the paint job leaves a lot to be desired!. But, I can't find much of anything as a guide to proper paint design and colors. Does anything even exist?
Any thoughts on this bike would be appreciated.

Wow. I haven’t been on here for quite a while. I started this thread almost ten years ago and people are still adding to it. Awesome.

I have a bike that I bought from a thrift shop in the early eighties. I was a young bike mechanic and I promptly refreshed the grease in the hubs, BB and headset. I rode it a very little and it has been sitting in my parents basement ever since. Lately I've been smitten by mid-nineties vintage bikes and I'd like this rather nice classic bike to find a new home.
