M of S rebuild codes
Richard, thanks mate..I remembered that I had this information:
"Under the Electrical and Mechanical Engineering Regulations, a code was stamped on all reconditioned engines so that any defective units or assemblies could be traced to their source. A code reference number consisting of symbols, indicating the repairer, followed by numerals indicating the month and year of overhaul.
The following reference letters had been allotted to workshops and commands [by 1944]:
COMMAND WORKSHOPS, ROYAL ELECTRICAL AND MECHANICAL ENGINEERS:
ALDERSHOT: ALD/-
CATTERICK: CAT/-
HIGH WYCOMBE, BUCKINGHAMSHIRE: HWB/-
MILL HILL [LONDON] MHL/-
BOVINGTON: BOV/-
CHILWELL: [Central Ordnance Depot] CHL/-
BICESTER: BIC/-
LINWOOD: LIN/-
GREENFORD/- GRE/-

*^ Vauxhall Motors Limited acquired land in Dunstable in 1938 [Luton News] as the precursor to building a new truck plant, Luton apparently having logistical problems being unable to cope with expansion. However, the plan did not proceed until the Ministry of Supply authorised the building of a new ‘shadow factory’ in Dunstable, possibly from 1940 for the building of the Vauxhall Model A22 Heavy Infantry Tanks, and other war work. This factory then turned to the rebuilding of military trucks under MofS contracts, though this was on a separate site from the Dunstable plants of AC-Sphinx and Delco-Remy & Hyatt. It was this site that was to become in the next decade the new Bedford truck plant: further land adjacent to the wartime works was acquired by Vauxhalls and work began in 1953, with the first Bedford trucks being produced for 1955 Model Year in 1954.
D.Ds.M.E. of Commands were to allot a serial number to each Command workshop in their Command which used the above reference letters. The appropriate number was to be stamped on repaired assemblies immediately following the reference letters, e.g. NOR/4/- that would indicate, say, Scorton workshops. The standard position for the code reference numbers on engines was agreed with the Ministry of Supply. In the case of other engines or assemblies where no special position was specified, the reference number was to be stamped adjacent to the makers’ serial number. E.g. AEC were to be stamped on the offside of the engine at the front end of the cylinder block."
