Positive it's stamped M-659 but the H 414 is H412, the m-659 is on the grip and under the rihgt side plate,I have dissasimbaly inst. for the 669 and all the parts look the same, so I'm thinking that they mis-stamped it. As far as the sre.# they still have the place to check the ser.# but it comes up as no # in data base. And as far as taurus goes my gun is not in there files.
