rebel,
Can't tell if there is a 480 code on the other side, there is something there but too small to read it without magnafing. The serial # is very clear, as a matter of fact you can make it out in the pic (6147D) and the slide has the same matching #. A friend took the same pictures to a gun show this weekend and was told by a vender looking at the pics he would guess $350 to 500.
