Golden State Arms was one of the companies cutting back the barrels of No.2 revolvers for the US market. Ads for the 2inch were in many magazines during the late 50's and early 60"s. The wood grips are original but heavily sanded to remove normal grooves in the wood. It may have some collector interest like the sporterized .303 rifles done by Golden State but they are not legitimate issued items.
I seen one of these for sale a few years ago at a gun show, the seller had it advertised as a rare experimental model and wanted $1000.00 for it. when I told him the story about these being done for the civilian market, he told me I didn't know what I was talking about.
