Looks like you got your self a nice shooter.
Most of the markings on the left side have been worn down which leads me to believe that its been refinished therefore takeing away most of the collectors value.
And for some reason the SN just doesent look right to me.
Also i'm getting this naging feeling that the frame has been replaced. The slide has the markings of M1911 A1 U.S ARMY on the right side and the remnents of the patent markings on the left side which all leads us to believe that it was US property at one time BUT the frame is lacking the usual proof markings and U.S ARMY markings. And for some reason the SN just looks hand stamped to me.
But i could be wrong, I dont know every thing. Maybe good ole Fluff or Tuner can stop by shed some more/better light.
All in all ya got your self a good shooter.
EDIT: Yup i think i'm wrong. Tuner, Fluff, anybody smarter than me could ya shed some light on this one. I would really like to know.
