Guys. I am looking for a 1917a1/1919 bottom plate that is milled instead of cast. I am working on a blue gun and the cast ones come out of the blueing tank red. The easiest way to tell is by looking at the u shaped cutout in the bottom front of the plate. On the milled ones the edges will appear sharp and on the cast ones the edges resemble sand. I am willing to buy, or I have a cast one I am willing to trade along with cash. I have some other 1919 parts as well if you need anything. Let me know what we can work out.
