For something like a bottom bracket spindle, I wouldn't be surprised if the item was catalogued, unchanged, for decades. For instance, when CCM revised the standard Triplex spindle in 1923, it went unchanged until it was discontinued circa 1942-1943. The racing version appears to have gone unchanged from 1923 to circa 1954. What I do know is that Walton & Brown were involved in crankset manufacture at least as far back as 1927 (per the attached 1927 advertisement) and that they survived into the 1950s as part of Brampton. It's conceivable that the subject spindle spenned this entire range.

like TMar said, it's very difficult to tell the age of those parts as they were used for soooo long
and they are so common, each old bike shops I have bought out in the past must have had 20-30 if not boxes full of NOS crank shaft like those and of different brands, seems like every brand made them exactly to the same dimensions so they would be interchageable

Thanks a lot for that info T-Mar. I appreciate. My Web search is yielding very little info.

I hear that. I have three of them. I think they're cool. Will give one to a buddy of mine and hang on to one or two for my stash.
