Recently ran across a receiver, stock, and forend metal and wood. Matching #"s but the barrel I find for ir will lack it it. All right GURUS: what info. do you need to determine gauge for this beautiful field. This gun is in emaculate shape with beautiful case colors and a few honest wear marks on the stock. Looks to be a small bore--definitely not a 12. Any help apprecieatied. Regards, Wes Hardin
