Condition Grade: Good to Very Good (Grade B-). The anodized barrel shows a deep, crude custom engraving of the numbers "Z0" scratched directly into the lower outer finish, contrasted by an exceptionally clean, bright, and shiny smoothbore interior cavity [Pre98 Antiques]. Dimensions are approximately 9.60 inches in total length with a 6.10-inch barrel. Features multiple small factory military markings including correct "WaA280" Eagle Waffenamt inspector stamps, a 25.5mm measured bore diameter, and the matching serial number 5103f stamped cleanly into the receiver plate. This lot consists of the standalone break-action signaling device as shown, without an original leather storage holster, cleaning rod, or transit box [1944 Militaria]. This military hardware artifact is a standard-issue World War II German Army Leuchtpistole 34 (LP34), manufactured in 1941 by the prominent factory Erma-Erfurt.
