Roy and Lagopus, I have no memory of measuring the chambers to see if they were actually 2 1/2", but I normally do this on all guns and would have remembered if they were different than stamped. Both guns had the odd marking, and since I have seen it on another Greener, I wonder if it might have been done at the Greener's request. Sort of an overload proof ? Serial No. is 55805, but barrels appear to be later. The heavy oak and leather case they came in had provisions for two guns with a total of 4 sets of barrels, but the "original" barrels were missing when I got the guns.

Lagopus, if you wish, you can send the proofhouse the picture and question, of I can if you can provide me with the proper address.
