I have a drawer full of cottered spindles, but lengths really vary. Do you have specifics for what you need, e.g., overall length, DS length, NDS length?

actually, all i need is a fixed cup, but i thought it might be a long shot asking just for the cup. the crankset is coming my way with everything but the fixed cup. might you have one of those kicking around?

I likely do though it would be good to know the manufacturer of the rest of the bits to ensure a potential match. Brampton? TDC?

just ordered it off of the bay this morning, so don't have it here to check. i know nothing about cottered cranks... this will be my first setup. it's a Williams crankset with everything but the fixed cup included.

What's the bike? Raleigh BB cups are 26 tpi, other English BB threads are the standard 24 tpi. They are not cross-compatible. Raleigh BB's are also a bit wider than usual, or at least many of them. So if the bike you want ths for is a Raleigh, you should be fine. If not, then I am not quite so optimistic.
On the other hand, BB cups are not specific to cottered or cotterless spindles; you can usually mix and match cups and spindles from different manufacturers .

I just took this one from an early seventies Falcon. It is listed on Ebay for $25.00 but yours for $15.00 + shipping if you are interested. My guess would be about $15 to ship...

thanks, randy! i have a bottom bracket set from neal that i'm going to try out when i bring my frame up from the dungeon tomorrow. now thanks to rhm, i'm not sure if my bike needs a 26 TPI or 24, so i'll verify that and get back to you by tomorrow evening. my frame is badged as a mercian, but it might be a faux mercian and maybe a raleigh. at least i got the frame for a good price...
