Mauser 1912/14: Flapper-Delayed Blowback
The Mauser 1912/14 is a rare automatic pistol featuring a unique flapper-delayed blowback system, mechanically similar to later roller-delayed designs. Developed as part of a unified pistol family, it required a 'cheater lever' for manual slide operation due to its strong delay mechanism. Production was limited to under 200 units, ceasing in 1914 due to WWI and the death of Paul Mauser.
