I have a Midland Demon hammer gun. 12 ga #8285x. Original nitro proofs at 13/1 and 2 3/4" chambers. 12 over the C but also marked 12/70. I doubt if all that is original proof marks. Steel barrels; I don't consider it an elegant gun so I was surprised to see that Demons were considered among their top grade guns. It is a very usable, light weight and good modern dimensions but hardly anything fancy. When it came in, the seller warned me "It has about every handling mark known to man." He wasn't exagerating, either.
