Need older small inner Campy chainring

Hi: I am a first time visitor and am in need of a few parts for my early 1970's touring bike. (Double butted with Campy dropouts with chrome accents) I currently have a campy triple (slotted Record arms) with 52/42/36. I would love to find a smaller inner ring...30 or 32 tooth for my 65 year old legs to climb hills. I switched to a larger spread on my rear 5 gear cluster but still need more for comfortable touring. Not sure of the BDC, but it measures 2-5/16" or 58.6m between two adjacent bolts. The crank arms are threaded to receive the bolts for this chainring alone. Used campy ring would be great but also any leads to a different brand new replacement would work just fine. I run an old Campy Rally rear derailleur so I have plenty of chain movement.
Thanks for any leads. I live in the central USA.

Welcome to the forum!

I hope you find the parts that you're looking for. Per forum rules any deal that you make has to be done in private. This might be an issue for you since you only have 1 comment on your profile and you need at least 10 comments to enable the Private Message feature in the forum. It may be to your benefit to post some comments in other threads to get over the 10 post minimum in order to communicate with others via PM.

Cheers :)

Draw a line between 2 adjacent bolts, then another perpendicular to that line to the bolt opposite-that's BCD.

Some info here-

Found the crank and 100mm BCD..aren't going to find any CRs for that(small)
