Dances:
Well, I've got to hand it to you. This is a new one! I can explain away threads on the outside as a suppressor attachment tool, but the inside simply would not leave enough wall space for the threaded cylinder to avoid being "shot"on firiing.
I have seen the muzzles on military arms drilled out in an effort to save a barrel with worn rifling at the tip, but threading the hole is not necessary in that case.
A blank firing device for theater or re-enactment?
Does the gun seem functional in all other ways?
Let's see what the others have to say.
Interesting find, and maybe someone on the forum has an award, something like "stump the chumps"...
