I'm in need of an 88 BCD Williams chainring in 46, 48 or even 44 teeth. It's chromed steel. I'd much prefer the 46, but could make the others work by fiddling with my freewheel cogs. I need the version for 3/32 chain; 1/8" versions are common but won't work for my application. See the photo, above, of a 50-tooth ring on my woodpile. I have a 3-bolt crankset, but there may have been some 6-bolt cranks as well, since some rings come with 6 holes. Either works with a 3-bolt cranks. As far as I know, most rings of this pattern were made by Williams, though Nicklin branded models also exist. Possibly others made them as well.

Not sure how much hope there is of finding one of these, but when consider some of the obscure parts that others are looking for I feel some faint glimmerings of hope that one will turn up in someone's parts box.

I have various items of value to exchange for such a ring.
