I used a fellow named Earl Case several years ago to checker a M32. He did a outstanding job and was certainly a better deal than most. What I remember about his web site was a M12, which in my opinion, was a work of art. I do not think he did the engraving but the carving and checkering was very nice. I will go on to say that there are lots of people good at checkering but I was impressed with his work, price and quick turn around.
