The Liliput was made by the August Menz Company in Germany during the 1920s, in several variations. It was introduced in both 4.25mm and 6.35mm (.25 ACP) and also later offered in 7.65mm (.32ACP). These were typical defensive pistol chambering at the time, although the 6.35mm version was much more popular than the 4.25mm one. They are simple blowback pistols, and competed against similar but more successful designs like the FB Baby Browning, Walther Model 9, and Mauser 1910.
