I just found a Mowrey .58 caliber Tree Rifle with a 22" barrel. It has the old style tumbler, but I purchased a newer style tumbler and hammer in case I ever have problems. The newer tumbler requires a small amount of metal work but nothing too difficult. The rifle is very accurate and it is one that will have to be pried from etc. etc. etc. I had one other Mowrey prior to this one, and found it accurate as well. What a nice, light, but powerful elk rifle.
