Picked this up at a Gun Show.
Winchester Trench Gun. Fixed Receiver Model 1897
It’s a 12 Ga 20″ with the 3 three grooved area for screws for the Trench gun Shroud
Appears to be un used, with grease still inside the bore, no markings on barrel from use Bluing is 98%
Has a 41- and index mark on the bottom of barrel and No proof marks any where on the barrel.
But …. seems to be strange. the Barrel is Marked Made in THE U.S.A and the 2 /3/4 CHAM CYL” is in different script.
Last Patent date isJuly 5 1910
What might I have here? Thanks

David, I’m sorry. I can actually load your pictures. I am not an expert and have never removed a barrel. It looks to me that it is a standard barrel for a riot or guard gun except for the 3 notches. The 41 probably is the year of the barrel? It could have been intended for a trench gun but it doesn’t have the US inspection marks. Barrel address and markings look OK to me.

41 is the barrel date. It seems to be a pre WWII barrel. It was just around the time of WWII that Winchester changed the barrel markings to include the “Model 97” designation on the barrel. Earlier barrels do not have the “Model 97” designation on them. But the replacement barrels usually have the Winchester “WP” mark on top and also a P in an oval which is the Winchester mark for a replacement barrel.
Is there any evidence of the barrel ever having a front sight bead?

Yes, the “41” is the barrel date, but you are incorrect concerning when Winchester added the “MODEL 97” designation marking on the barrels. That change occurred in the year 1930 (near serial number 850000).
The barrel in question is a conundrum to say the least. I believe that it was not proofed because it was not intended to be a mail order replacement part. Instead, it was an in-house part to be used if a gun was returned for repair, and it would have been proofed after installation.

Bert-
Is it possible this barrel left the factory during a sell-off of “obsolete” parts or following one of the ownership changes? We all know Winchester never threw anything away but I suspect they sold off excess parts inventory now and then.

That is what I suspect it is… a parts sell off after the Model 97 was discontinued in the late 1050s.
