  2.  @spookyshadowhawk6776  iirc, the Vickers in the Boer War was a 1 pounder, single barrel, 37mm, that could be mounted on a carriage similar to that used for a Gatling, or post mounted on a vehicle or ship's deck . That begat a 1 1/2 pound/37mm, which was used as a light AA gun by the RN in WWI, which begat the 2 pound/40mm. The early 2 pounders, Mk I, Mk II, were single mounts and apparently suffered reliability issues. The later Mk VIII, used in multiple mounts, was more reliable.
