My Favourite British gun is the Lee Enfield, my favourite british revolver is the Webley Mark 4.
Some British guns in WW2 such as the renouned rifle the ‘Enfield No.4 Mk.I.’ that was used from 1902 through to World War Two.
It was the English favourite gun in WW1 and one of their favourite in WW2.
At the start of WW2, Great Britain was badly under armed. The disastrous campaigns in France in 1940 which resulted in the massive evacuation under fire of British and Allied troops from the beaches of Dunkirk and Calais further depleted her inventory of arms. Massive shipments of military arms from the U.S. Government and sporting arms from private American citizens helped to ease the situation somewhat, but it was the amazingly fast production program that the British had put into effect as early as September 1939 that saved the British Army of poverty of Weaponary. The No. 4 Enfield was produced in a wide number of variations, most having to do with ways to cut production costs and time.
