hi guys; i didn't mean to stir up any contention, i got the humor. the subject was thoroughly flogged on a previously posted subject that was not available to me through the archives, i probably did something in error. however -- olefogy,-- i now have 3 1920 commls., the subject piece is indeed 9mm. -- i'll be picking up the trench gun from charlie tomorrow (saturday), i cannot figure out how that "sawback" bayonet fits perfectly onto the winchester shotgun!!also the bayonet is in a circa 1870 leather scabard with "pioneer bataillion" stampings on it. any input here could decide weather or not to spring for the bayonet! regards to all; --john--
