Pete/Rev,
Unfortunately all that I have left of the C30 is the receiver. It's a parts gun. I believe that Daryl is correct on chain damascus. I have not puzzled out the image posting tricks, but here's a photo URL:

However I pulled the locks off tonight and found that both locks are the v-spring style and both are stamped 32251 (no final 2). I suspect that the extra digit in the receiver number was a factory slip-up. I'm pretty sure the correct serial should be 32251 as marked on the locks.
Here are some serials and sketchy notes on other Meriden/Aubrey doubles that have passed through my gun safe in recent years:
12 Ga. 3495 A.J. Aubrey damascus hammer gun
12 Ga. 12382 A.J. Aubrey steel hammer gun
12 Ga. 12412 A.J. Aubrey T30 hammerless, extractors
16 Ga. 78425 Meriden K32 Krupp hammerless, extractors
