I have been rebuilding a parts revolver and have all the parts except the barrel wedge. The gun is a 36 caliber C&B and I have tried 2 wedges from Dixie, both were too small. The mark stamped on the left side of the frame is a Centaur, a sideways "T" and an arrow(?). My thought is that it may be a Spanish made gun. Any thoughts? TIA. Emery
