My, my, must have touched a nerve. I believe your original question was:
"Question: Is this just a basic mauser action/ trigger assembly? (The trigger in the action doesn't look like a regular mauser type trigger.) Can a mauser style trigger be used in the Interarms action? I'm sorta lost on the Mauser stuff."
I was simply implying that your gunsmith should have been able to answer that question when he looked at the rifle.As CAFR said earlier--"A new BOLD can be fitted to just about any Mauser for $100.00 or less".
