A standout example of an early DWM Model 1900 Swiss military contract Luger that was re-numbered in Switzerland. Discussed on page 27 of "The Swiss Variations" by Fred Datig, 100 of the "E" prefix serial numbered Swiss military contract Model 1900 Lugers were re-numbered to an "A" suffix series that ran from "5001A" to "5100A." This specific pistol is listed by serial number on page 30 as having an original serial number of "E643." Features fixed blade front and notch rear sights, Swiss "cross in sunburst" crest over the chamber, and "DWM" monogram on the front toggle. These Swiss contract DWM Model 1900 Lugers have early dished toggles with toggle lock, a flat breech bolt, grip safety, no stock lug, flat mainspring, and fast taper barrel. The left of the barrel, left of the barrel extension, and rear toggle are marked with Swiss cross proofs, along with a "cross/V" proof and "P31" over-stamped onto the extension, signifying release to commercial sales in 1931. With matching serial numbers on the barrel and frame, along with matching"43" partials on small parts including the extension. Fitted with checkered walnut grips numbered "643" on the interior. Then nickel finished magazine is fitted with an aluminum inset hardwood base. Includes a "G.WEBER/SATTLER/MENZIKEN" and "22" marked leather holster with magazine pouch attached on the flap and a leather shoulder strap.
