Nice looking shotgun !! Is that a Winchester Model 12 handguard ?

It appears to me that it is not. However...I need to have an actual expert authenticate.

should have a S stamped on the side of the bayonet lug.

Chuck: There is an "S" stamped on it. Thanks.
I have suspected its parts are all original but it needs to get checked out by someone more informed than I to authenticate.

Not all Stevens bayo adaptors are S marked. Only the late made trench guns have S marked adaptors.

both my 530 and my 620 have S marked adabtors.
the 530 is original, not sure of my 620, likely a parts gun.

Hi Chuck. If your guns are original, they are likely late made guns. There was a contract for the Stevens guns made in late 1943 that provided the bayo adaptors were to be S marked. Same with the Winchester bayo adaptors. So, it is likely that only guns made after that time had the S marked adaptors. I can't remember the exact serial number ranges right now, but my recollection is that the 530 trench gun serials over 67,000 and the 620 serials over 26,000 had the S marked adaptors. I may be a bit off on theses numbers, but I can check later today and give you more accurate numbers.

Correction. I meant to say the 520-30 trench guns, not 530.
