The black diamond stock would be very suspect on a gun marked "Skeet". To get a black diamond stock from the factory, a Trap Grade gun with a skeet choke barrel would have normally been supplied. The metal refinish doesn't appear to be well done, but it may be possible to repair it, at some cost. The wood would have to be replaced with a Skeet Grade stock, probably with scant grip to be proper for the period. The gun would not satisfy a serious collector.
