traverse=The Ordnance QF 6 pounder 6 cwt Hotchkiss Mk 1 and Mk 2 was a shortened version of the originalQF 6 pounder Hotchkiss , and was developed specifically for use in the sponsons of the later Marks of British tanks inWorld War I , from Mark IV onwards.History
The original 6 pounder had turned out to be too long for use with the current British heavy tank designs, which mounted guns in sponsons rather than turrets, the muzzles of the long barrels sometimes digging into the mud when the vehicle crossed trenches. The 6 pounder 6 cwt Mk I of single tube construction was introduced in January 1917 in the Mark IV tank. The Mk II gun was developed at the same time, having a built-up barrel construction.Hogg & Thurston 1972, Page 39]
