9/26/17 - This is a 1913 Sauer in original condition. It is all correct with about 92% bluing remaining. There is some muzzle wear on both sides of the slide, as well as some thinning/browning on the front strap. The front strap is also marked Pw. B, but not positive the significance of this proof. Nice mag and excellent grips. Crown/N proofs. Vibrant and beautiful fire blue on the top of the slide and the safety remains. Minty bore.
