Usually im a pistol person but lately Ive been shooting alot of clays, useing one of my fathers shotguns becuase ive never had the need to buy one. While I was borrowing one of his Mossbergs I noticed another bag and pulled it out to see what it was. I always knew he had a older shotgun so I pulled it out and its stamped "Nitro King" in scrolling on the side. finish is ok, wood in is good condition, looks to be 12 gauge. Im assumeing it fires the older kind of shells black powder of sorts if I remember correctly. I gave it a cleaning and put it back, its single shot break barrel also. The only thing on the net ive found close to it so far is the "King Nitro" by Sharpleigh hardware co. dateing it back to the 20's-40s. I would just like to know more about it and if its going to drastically reduce its value if it is re-blued, because it could use it.

Oh, and ill throw this in too, Where is there a list of all the Mossberg 500 series shotguns and what model number is associated with model. For instance what is a 500AT or 500AB?

Thanks,
