Just picked this up at a local antique shop this morning. I think it is a Model 1 Second Issue .22 caliber 7 shot revolver. Does have some problems with the cylinder not rotating properly, but it has great eye appeal with lots of silver finish and bluing remaining, and great finish on the grips. What also caught my interest was the "2D QUAL'TY" markings on both sides of the barrel flat. Think i read somewhere that while these guns were sold at a discount then, they bring a premium now. Despite not working properly, it will look great in the collection and hopefully $225 was not a bad price. Are there any ways to clean some of those rust spots without harming the bluing?
