Single brass bead sight on the concave solid matte rib, with "J.P.

The frame is finely casehardened, with "MADE IN PRUSSIA" on the water table, the Sauer marking on either side, light scroll engraving, dual triggers and an automatic safety. Checkered splinter forearm and knob grip stock, with an unmarked inscription oval on the underside of the stock and a serrated horn buttplate.

Very good, with 70% plus original blue finish, showing the start of a brown patina near the breech, along with some mild handling marks and edge wear. Over half of the bright original case colors are present on the frame, with some fading near the front and on the tangs. The stock is very good, with light dings and scuffs. Mechanically very good.
