Not to rain on anyones parade, but that gun definetly has been refinished. No Erfurt is that shiny as issued, they are rougher finished than DWMs. The top view of the chamber area is really shiny. Check the safety marking for paint, check the inside of the receiver forks and top of the inside of the frame to be polished white steel, not bluing. Check the inside of the mag well in the frame, it should be polished white steel, not blued. The strawing on the different parts are not consistent in color, another thing I would look for. The bluing on the inside of the frame ears on the outside of the frame is not consitent with the high areas, it looks like it was bead blasted then the high areas polished and salt blued. This pistol should be rust blued and it just doesnt look right to me with what I can see. A 1914 Erfurt would not have a notched top receiver unless it was for a 1914 Erfurt Artillery Luger. The common notching practice did not start until 1916 with both standard 4" and 8" Lugers having this notch in the top of the receiver. Please take my comments kindly as they were intended that way.
