During 1944, the US and UK cooperatively ran a major effort to drop arms and equipment to French Resistance forces in preparation for the Allied landings in France. It began as Operation Carpetbagger with night drops from B24 Liberators in January 1944, and escalated into the summer. Eventually a number of massive daytime drops were made, totally more than 800 sorties and dropping 2.7 million pounds of equipment. The single most common firearm dropped was the MkII Sten, but containers also included Brens, handguns, M1 Carbines, bazookas, and No4 Enfields (along with ammunition).
After the country was liberated, the new government tried to collect up as many of the weapons as possible. They didn’t get them all (not by a long shot, actually), but many were put into government storage, including this No4 Lee Enfield. It was marked with a “PP” property mark and inventory number, and stashed away until being sold as surplus recently and imported by Navy Arms.
