I picked up an 1891 Loewe Berlin Gew 88. The Receiver is marked LOEWE BERLIN 1891 S. The serial numbers match on the barrel bands and the magazine.
The barrle cover doesn't match the receiver. The blue is about 99 percent. When I shine a flashlight on the receiver I swear it looks like it was gold leafed. The barrel looks like it was never shot. The front sight is a mismatch. I found a repro cleaning rod for it. It is missing the rear sight slide. The bolt is a Turk. It is all matching the body is marked 863, the cocking piece, firing pin nut, bolt head and safety all mared 63 in arabic numbers all 5 parts have the Turkish Crescent Moon on them. This was
probably a replacement bolt.
