WTB: 5-pin TA chainring for Williams cottered crank
Hi folks,
I am using a cottered Williams steel crank for my '51 Wasp, and I want to use longer crank arms, so I've found a new set of crank arms, but these require a 5-pin chainring instead of 3. So I am looking for a 50.4 BCD 1/8" or 3/32" 46T chainring, TA-style. 48T could work as well, but I would prefer a 46T for good gearing with a four-speed sturmey-archer IGH with an 18T cog.
Thanks.

I may have a cosmetically challenged steel Williams if that's of interest, can look tomorrow.

I’ve had a couple of those rings for 1/8” chain, and both were 50t. I’m wondering if smaller will be really rare. That said, shouldn’t have a problem running a 1/8” chain on a 3/32” ring.

I have a very nice 50t available. If you have zero luck with the other sizes and are interested, hit me up. I can help. Cheers!

Sorry, the only available one I have is an NOS 48 tooth 1/8" without any markings. Looks like a Williams but perhaps a Nicklin?
I'd like $30 cdn plus shipping and will include 5 new square bolts.

TA still sells and presumably makes chain wheels that fit your crank arms (and many others) - https://specialites-ta.com/128-pro-5-vis. Velo-Orange also sells outer and inner rings.
