I have an Iver Johnson Machine & Cycle Works, single shot 16ga. Belonged to my Grandfather.
I've had it re-done, blued, stock & forearm. I also had the receiver case hardened to match the original. Turned out great!
Got a couple of old Iver-Johnsons in the collection, some nice old antiques. LOL, can you imagine getting a functional NEW gun for $6?
