Imperial Luger Pistol manufactured at Erfurt, the Prussian owned arms factory, during WWI. The chamber is dated "1918" and the toggle is marked with the distinctive "Crown/ERFURT" logo. The pistol has a dull blue finish with straw colored small parts. The grips are finely checkered walnut. The pistol serial number and suffix located on the front of the frame. "1139" is stamped on the bottom of the barrel and the left side of the barrel extension. The partial serial number, "39" is stamped on most of the small components including the inside of the grips. All of the serial numbers match with the exception of the magazine. The right side of the receiver is stamped with three "crown/gothic letter" army acceptance marks followed by the Imperial eagle and preceded by the "crown/ RC" Reuisians-Commission rework stamp. This proof indicated that this Luger failed final inspection due to "out of tolerance" parts. The rework mark is also stamped on the left side of the barrel over a crown/gothic letter proof and the Imperial eagle is stamped on the right. The left side of the breechblock is also stamped with the Imperial eagle. Typical of Erfurt pistols, a small "crown/gothic letter" acceptance mark is stamped on all of the small parts. The magazine is nickel plated with a wooden base numbered to another gun and the back strap has a stock lug.
