Nebraska, I've got two 39M's made in 1982 and they both have the black trigger. Some years had the black trigger instead of the gold trigger. Another 39M I own, made in 1976, has the gold trigger. Those screws on the top of the receiver are identical to those on my 39M's. Your rifle is, however, missing the front sight hood. The correct replacement would be one with a flattened appearance. Nice rifle!
