Hi Bill, the sealed-8 .22lr I.J.'s serial number is N195** and think it is a SNUB MODEL 68S (has 2 1/2" barrel)? The hammer spring is missing and the trigger doesn't seem to have a spring either (flops around). Are there substitute springs from modern revolvers that would work? The revolver was in poor condition, full of rust but after cleaning it the barrel and cylinder look fine. I still haven't figured out how to remove the cylinder. I would like to disassemble it and see whether it's worth restoring to shooting condition. Any advice much appreciated. Thanks!
