This is my opinion, and considering the fact that I worked with steel and iron most of the last 20+ years I would say that I am about right.
The gun was handled that's for sure, it was in military depots for the last 50+ years and didn't just sit in a crate; like I said in a previous post the guns were inspected periodically, cocked and dry fired, moved around, maybe even taken apart. After arriving in Canada they probably saw more handling and dry firing than over the half century spent in storage. And they were fired at least once at the factory.
Therefore, my opinion is this: there is no pristine, as off the assembly line guns ending up here. They all have been handled, played with, dry fired, etc.
You may think that what I say is BS, but unlike most of you I have spent time in the combloc military and I have I good idea how things are done there.
