Interarms Mark X shotgun

Question
I have inherited my late father in laws Interarms Mark X 12 gauge Semi-Automatic shotgun. Upon taking it apart to give it a good cleaning I discovered that sometime in the past the barrel had been welded in the area where it goes into the receiver. A good thorough job was done, cleaned up nicely and deburred but I'm not very comfortable with using it like this. My question is, I've looked over the shotgun looking for more info so I can attempt to purchase a new barrel. Any ideas as to where I can purchase one? Greatly appreciate your help with this.

If they don't have it listed on the web then try calling them. They often have more than shows online or can point you in the right direction.

Hope this helps. Good luck!
