Welcome aboard.

Normally frame / serial numbers are few and far between and often get overlooked on here because normally they don't lead anywhere.

However in this case as it's pre-war and you had the basic info needed (Westfield, Columbia, Clipper) the info was actually quite easy to track down.

Thanks to a guy called Mercian over here at The Classic & Antique Bicycle Exchange

It appears "B" was the date letter for 1935 (you need to scroll down a lot on the page i linked)

Some great info and images of various Westfield Columbia's, good luck with the restoration

  • @Andrew, I actually hadn't seen that site but i will add the link to my answer so the OP has a couple of places of reference points. The link i posted has only reference to "B" being 1935, unfortunately Colombia have a possible 2 answers 37 or 56? Best to reference both sites and let the OP have browse.
