It appears that the date stamp is [AP] (1986), starting bid $125, no reserve, and no bids so far. Closing date is Christmas night so this would be a good one to watch.
That is not a bad pistol to bid upon, especially if one collects ASM pistols.
I won't be a competitor because I have a Pietta G&G .36 [CN] (2015) and I doubt ASM parts would interchange with my Pietta 1851 Navy .36 pistols.
Since it is listed as a "Brass frame reproduction ASM Colt 36 caliber", it would seem that the seller does not perceive this as a G&G repro, almost like the early Italian manufacturer who produced an "accidental" Schneider & Glassick .36 using a brass framed 1851 with an octagonal barrel at about the same time. Since the seller posted only 3 pictures, if I was bidding, I would contact the seller about loose arbor/cylinder pin and/or damaged nipples. It seems to only have a very slight turn ring on the cylinder, so either the timing is good or it just sat around getting a good brass patina, especially the dark trigger guard (it appears to be brass if looking at the front strap). All of the screw slots in the photos appear very good, not turned.
Hope someone here scores well with their bid.
