Captain, I saw the auction you're talking about, almost bid on it myself. It was an ASM Walker with Colt marked barrel and cylinder and A-Company military markings. This is the second one I have seen, unless this is the same one coming around again. I believe this is nothing but an ASM Walker and stamped by ASM, the fact that it has military markings probably make it some sort of special edition. I have a Colt marked ASM Walker just like it but it doesn't have military markings, just a regular ASM serial number and it also says Richland Arms on the side of the barrel. The barrel address is not backwards since the original Walker's and 1st Model Dragoon's read breech to muzzle; 2nd and 3rd Model Dragoon's read muzzle to breech. 2nd Gens and Sig Series are the same way.
