Bottom Bracket Spindle Question.
I have a few different bottom bracket spindles. I'm not too sure what they'll be good for, and/or their suggested use.
Also, I'm wondering their orgin, who made them and the country.
Thank you.
The first spindle is labeled "YST-7NL" and "CR-VD"
The second is "3RR-B", "Cr-Mo" and "K-3"
I also have a KoR bottom bracket 1.37x24. What I am wondering about this bottom bracket is what it was originally used for.
I have a SKF sealed cartridge bottom bracket that has "BSA" stamped on the left side. Stamped THUN 1.37x24. What's up with this one as well?

www.sheldonbrown.com has, if I remember, a crib sheet or similar listing BB spindles, their lengths, etc. I think more information might also be forthcoming in the Classic and Vintage forum here. I know the stampings on the spindles relate to their size and their offsets for different cranksets (eg, MTB versus road).
