Right up until 10 years ago, CVA sold guns with the identical lock plate shape. In the early 1980's, a person could buy one of those locks new for around $10.00 a slightly better lock with a fly in the tumbler was $12.00. Good news is that CVA sold guns with that lock shape for 25 years and Traditions still sells guns with locks that have similar parts. That lock is not the extreme crap that Jukar first put out. Again, it isn't really the breech that is bad, just the early locks that generally went with them. Some early Jukars were made that way and real early ones had the bolsters welded to the barrel material. Some guns are not hooked breech systems but still had the bolster cast as part of the breech plug andd the seam is still visible just ahead of the bolster. TC percussion breech plugs have the bolster cast into the breech plug and you will most likely see the seem just ahead of the bolster where the cast breech plug meets the barrel. Nothing like looking for a part for a cheap lock that is no longer made. Suddenly you find the hammer dropping on the nipple because the notch gave way. Tumblers were case hardened and often if not hardened properly, the full and half cock notches wore off within a few shots.

It is that the locks made to go with them generally had very poor quality lock parts made for as cheap as possible. They aren't dangerous with moderate loads. Some of the very early Spanish guns had the bolsters welded to the barrel. Some percussion patent and hooked breech guns have bolsters that are cast as part of the breech plug. The extension sticking up from the barrel that holds the nipple is welded to the outwer wall of the barrel. A drum and nipple has a round metal drum sticking out from where the touch hole would be on a flint lock and then the nipple is screwed into that round metal dum.Ī civil war Enfield and the Union Springfields have bolster breech systems. A bolster breech is a breech in which a piece of metal is welded to the side of the barrel flat to have a place for the nipple to screw in.
