A rare FN made AC marked slide used by byf on this 1944 dated (1945 made) pistol. Byf made only about 1,000 of these pistols with the FN supplied slides. All noted production was in the b - f serial number block, placing this one right in the middle of that production. It displays the dual tone finish of having a phosphate frame and slide, combined with a blued barrel. The phosphate finish is even and smooth, showing no abuse, pitting or major detriments. I would rate the finish at around 95% with just honest wear. The jvd marked mag appears to have a phosphate follower as it is a little rougher and doesn't appear to be blued. If you are a serious P-38 collector, you know how tough to find and desirable these are and it would be the centerpiece of your collection. Please contact me with any questions. More pix upon request. Price reflects cash payment. I can accept credit cards with a 4% surcharge. Must ship to an FFL/C&R.
