hate to burst your bubble ,but i think record checks happen 2 times a millenium in the states ,there talking about greg miller of rigby US, all his records are in texas and the company is in calif. they do not give out any info on serial numbers ive tried many times they say they will get back to you but it never happens , maybe you will have better luck i just bought a 400/350 and couldnt get any info...paul BTW was that gun you have from greg martins auction ?
