This is a nice example of a scarce "Liliput" pistol as manufactured by F.W. Heym of Suhl. The 4.25 mm Liliput pistol is one of the smallest semi-automatic handguns ever made (the Kolibri is generally considered the smallest). The barrel has a crown/N commercial proof on the left side and the left side of the frame is marked ""LILIPUT" KAL. 4,25 / Modell 1926 F.W. HEYM SUHL". The trigger and magazine both numbered to the gun. With box and a 50-round box of 4.25mm ammunition.
