Hi RWBlue, yes, I'll take a closer look when it is in hand.. As for interchangability, most of the time, most of the assemblies, will interchange? But if you do enough of this, you'll find a sizable percentage will not! The Navy I just completed for Ed, wouldn't go together no matter what i tried! I was almost like the parts repelled each other!!! I have four shooters, and I'm pretty confident one will work... Anxious to get a look'see and report back! Best to you, til.....lat'r....GT
