The first set of pictures were done under better lighting and that was what I was going with, as far a machining I have seen some very pretty looking sights and some that were done with old tooling so they had that not so polished look before they were finished.Phil, what leads you to believe this is legit? Look at the NM/2A and how its stamped nothing like hammons, nothing. Nothing like the one I have. I am almost certain based on the new pictures it is chinese or a knockoff from some other entity. The milling marks, look more like cast marks to me.
