Don't you mean the M1917 bayonet used on both the M1917 Enfield and Winchester M1897? The M1917 bayonet was chosen for the trench gun because it was manufactured in greater numbers compared to the M1905 bayonet. I do wonder if there are any trench gun bayonet mounts which can carry the M1905 bayonet.While I had one of the Norinco Trench Shotguns (copy of the Winchester M1917 aka 1897 pump with a handguard on the barrel and a bayonet mount for an M1903 springfield bayonet) and the work was decent, I'm not sure I'd be willing to trust a P08 copy.
Probably do mean that, I don't think I ever heard which bayonet the shotgun was supposed to have.Don't you mean the M1917 bayonet used on both the M1917 Enfield and Winchester M1897?
