Well, I was again in error. There is an importers name. The first world is so ill stamped to be illegible.
XXXX Arms Company, Gardener Mass. Model 226
The only Arms Co in Gardener Mass that I know of is H&R. Three letters and this one seems to have four.
There is a D2 A4 D/1 (D over 1) and 2/4 (2 over 4)
I talked with master gun smith, Stephen Hutton about the gun. He was unaware of the model as well.
I think I am passing on the gun. If some wants it, email me jmann@worldpath.net
It is a very nice 20 gauge and low money for an almost unfired gun.
Thanks, again, for the help with this mystery.
Best,
John
