OP GLS Sidelock Joined: Mar 2011 Posts: 4,199 Likes: 639 Lowcountry, GA	Did British gunmakers adhere to .729" for 12 ga. or was there a range?� Is there anything in these proof marks to suggest exact diameter?� Does the diamond with 12 and "c" in it have significance other than gauge or range of manufacture from 1925-1954?� Thanks.� Gil
