I have a 52t ring in good condition I sent you a PM, let me know if of any interest

cant speak for definite, but i reckon 42T is the smallest in 130 bcd to accommodate for the varying diameter. 36T is certainly 110BCD MTB stuff. If you do get a 39 in 130bcd, please let me know and I too can start hunting.

I think most had 40t on the inside
I've quite a few of outer and inner rings available in different colour finishes.

Not seen a 40t myself. Standard ring combo from that era was 42, 52.

 

[Inmish Ed]

Just checked, I've 40t, 42t and 52t

I've got a pair of what look like unused ones in natural finish. I think from memory they are 52-42 but I'll need to check in the morning. If you're interested Malc, PM me.
