So there was a gun buyback in my neck of the woods today and a few friends and I set up along the road with signs to get people to sell their guns to us instead. One of the guns I managed to snag today is a Spanish Eibar 455 made by Trocaola, Aranzabal y Cia. According to my research, this means that the gun is an Old Pattern No 2 Mk1 made for the Brits during WW1. I think I did well overall considering that I paid $`00 for it but I have found that the cylinder freely rotates with the hammer down. Since i would like a fully-functional revolver, I would like to get it fixed up for some mild plinking. Anyone know what the issue might be?
