Inert Post-WWI British MKV Lachrymatory Gas Grenade with Early MKII Fuse – Converted to Coin Bank with Penny Inside

Add a unique piece of military history to your collection with this inert post-WWI British MKV lachrymatory gas grenade, featuring an early MKII fuse. This grenade, originally designed to deploy tear gas (likely CN gas) for crowd control or tactical use in the 1920s, has been deactivated and repurposed into a fascinating coin bank, complete with a penny inside. The MKV was a significant design in the evolution of chemical weapons, developed after World War I and removed from service by 1940, making it a hard-to-find artifact from the interwar period.

This particular grenade retains much of its historical character, with a weathered gray finish showing traces of the original paint and a partial lot number stenciled on the bottom band. The body features eight side vent holes, originally intended for releasing gas, though it has been filled with an inert substance and can never be used again. The early MKII fuse includes a short spoon, typical of pre-WWII designs, with a WWII-era replacement pin and ring, adding to its historical authenticity. A slot has been cut into the side, transforming it into a functional coin bank—a creative modification that enhances its display appeal while preserving its military heritage.

This grenade is in good condition for its age, with expected rust and wear that tell the story of its nearly century-long journey. It’s a perfect conversation piece for collectors of WWI and interwar military antiques, or anyone interested in the evolution of chemical warfare technology. Fully inert and safe for display, this item complies with all regulations for deactivated ordnance and is legal to own within the United States (not available for export).

• Condition: Good, with rust and wear consistent with age; fully inert and modified as a coin bank with a penny inside.
• Dimensions: Approximately 4 inches tall, 2.5 inches in diameter.
