Bought my first two wedge half stock 45 at estate auction. Removed barrel and rear wedge is fake, barrel has one under lug. Is this common. Don’t know age of gun but guessing by the lock someone put together within last 20-30 years. Maslin style with Spain stamp. Barrel has no markings of any kind. Barrel is 42” long, 1” wide. Gun is 57 1/4 “ overall , 11.8 lbs. After getting gun home and inspected I am very happy with purchase , bore is spotless no pitting anywhere on gun and can’t wait to shoot. Just confused about wedge.
