I picked up a Springfield .45 used A1 parkerized used today. The gun came in the orig. box which is cardboard. The gun is about %98 and I paid $495 for it. The last Springfield I bought new about 4 years ago came in a plastic box and was marked Brazil on the frame forward of the trigger. This new purchase gun has no Brazil mfg. mark I can find. The literature that came with the gun talks of Omega models out of production for about 10 years I think. Do I have a made in USA gun?
