The only reference I can find to a maker is on this site:- http://www.btinternet.com/~ian.a.paterson/equiparmourtanks.htm ..suggesting Leyland Motors started things off. (..still not convinced myself.! ..I'd wait for Alexander. .gif ";)") ) |

Rover, Leyland, Rolls Royce and the Birmingham Railway Carriage and Wagon Company appear to have had a part in the manufacture of the Cromwell tank. The introduction of the Cromwell tank centred around the search for an engine that could replace the Nuffield built Liberty engine. This eventually turned out to be a de-tuned Rolls-Royce Merlin aero-engine without the supercharger and with the light-weight alloy castings replaced with cast-iron. The engine was re-named the Meteor for tank use. Leyland produced the heavier cast-iron crank case castings for the engines. Rolls-Royce would have had problems in producing enough engines for tanks in addition to those for aircraft use so they agreed with Rover for them to produce the Meteor tank engine engine and Rolls-Royce took over the development Rover were doing on jet engines. Rover as far as I can see did not produce the Churchill tank itself. Where the suggestion came from to use the engine developed from the Merlin seems to be unclear both Leyland and Rolls-Royce are mentioned and its quite possible it came from both sources. When the first tank prototypes with the new engine had shown the idea was a good one the Birmingham Railway Carriage and Wagon Company was approached to do the design development and manufacture of the tank itself. Although its almost certain the Cromwell tanks were made at more than one location the Birmingham Railway Carriage and Wagon Company appears to be the main manufacturer with Rover making the Meteor engines. A good amount of first-hand and detailed information is available here look for 'Cromwell tank' about halfway down. Link to "www.rrec.co.uk" I can only suggest applying 'Birmingham Railway Carriage and Wagon' as a maker's name for the Cromwell. -- Last edit: 2006-07-09 13:19:44 |

Let me give some additional information to Sunbar's comment: This film plays during the British retreat in North Africa, some time between mid 1940 and mid 1942. It would be too early for these tanks, but they were deployed to North Africa at a later time. So that's not too bad for a film. The specifications for this tank design were drawn up in late 1940, designs by Nuffield and Leyland submitted in 1941. As from the outside they looked (almost) identical we have three different versions: 1: Nuffield A24 Cruiser Tank Mark VII Cavalier (with the Liberty engine) 2: Leyland A27L Cruiser Tank Mark VIII Centaur (again with the Nuffield Liberty engine, as the Rolls-Royce engine was not yet available) 3: Leyland A27M Cruiser Tank Mark VIII Cromwell (with the Rolls-Royce Meteor engine) The later Cromwells had a welded hull, so this one is an earlier type. In the beginning a 6 pdr. gun (57 mm) was used which was later exchanged with a 75 mm gun, which we see here (but not originally used in Africa). This upgrade was not performed on the Cavalier tanks ... so one is out! The upgraded Centaur would then be the Centaur Mk.III, the upgraded Cromwell the Cromwell Mk.IV. Additionally the Centaur was upgraded with the Meteor engine and then renamed Cromwell Mk.X, later renamed again to Cromwell Mk.III, and with the gun upgrade to Cromwell Mk.IV. The Cavalier was produced from 1941-43. The Centaur was produced from June 1942 to 1945. The Cromwell from January 1943 to 1945. As the tank in this image has the 75 mm gun and if we assume it has the Meteor engine it would be the: Leyland A27M Cruiser Tank Mk.VIII Cromwell Mk.IV It is true what Sunbar says that the Birmingham Railway Carriage and Wagon Company took over the production but all my references still name Leyland as the producer. -- Last edit: 2006-07-09 15:01:16 |

Isn't that a little big name for one vehicle?  |

Well, its a tank, it deserves a bigger name than, lets say, a teeny-weeny SUV.  I think you need to be British to actually use two mark numbers in one name and finding that perfectly normal. .gif ":)") |
