RAF Mechanical Transport - AP2782A (Section 1) - General Information

The following has been adapted from the actual content of AP2782A but elements have been omitted where they are not relevant to the way the data is presented on the site.



The publication was divided into 32 sections, Sections 1 to 16 inclusive being contained in Cover A and the remaining sections in Cover B.

Sections 1 to 3 inclusive contain indexes and notes to assist in reference to the vehicle a pages, together with general information concerning RAF vehicles, vehicle equipment and notes on wheels and tyres

Vehicles are grouped in separate sections according to their operational uses; thus, all Ambulances are listed in Section 4, all Photographic vehicles in Section 27, etc.; vehicles in normal use are covered in Sections 4-16 inclusive; others of a specialised nature are listed In Sections 17-31 inclusive.

The final Section No. 32 is provided for the inclusion of any vehicles which, on account of their unorthodox features, cannot be readily classified in any preceding section.

Imported vehicles of Canadian and US origin are grouped with their corresponding British types and will be identified as such in the relevant entry.


Because the layout of the data on this site is different to the way in which it is presented in AP2782A the inclusion of this information here is considered irrelevant.


The data for each individual vehicle are listed as a separate entry within the appropriate section. Where possible a photograph or colour profile of the vehicle has been included for each vehicle.

The information given in each entry consists of :-

All specifications and body data must be regarded as typical. They do not necessarily apply in all details to every individual vehicle of that particular type.

Many chassis are fitted with several different body types. To facilitate reference, the outline chassis specification is repeated for each type. In certain instances, notably Mobile Training Schools (Section 23) and Signals vehicles (Section 30), a deviation is made from this system on account of the multiplicity of body types and the various combinations of bodies and chassis. In such instances data entries applicable to chassis only is given at the commencement of the section, followed by data entries giving outline specifications of the various bodies used and then a third set of entries showing chassis/body combinations.


To ensure the rapid and certain identification of each of the various vehicle types it is essential that the designation of each type should be comprehensive though brief. To this end, vehicle nomenclature has been standardised on the basis detailed below for use throughout this publication.

(i) For prime movers :-

 Make; carrying capacity (if appropriate); total wheels x driven wheels; maker's model designation; additional Government designation (if any). These particulars are given in the order specified, the designation concluding with the word chassis except where a complete vehicle, i.e. chassis and body, is the product of one firm, in which case the type of body is indicated.

Examples: -

(ii) For trailers: Make; load-carrying capacity; number of wheels.

(iii) For vehicles with specialised bodies: Each type is treated on Its merits.

In certain instances a vehicle may be listed in two different sections. This double entry has been made to facilitate reference in cases where the vehicle performs a dual function or where the official nomenclature is less widely known than some a1ternative name.

Definitions of Terms and Abbreviations used

WD SIMILAR     This note indicates that a similar type of vehicle is operated by the Army, but does not necessarily denote that both types are identical in every respect.  For example certain RAF vehicles are fitted with vacuum trailer brake connections, etc, which may not be fitted to their WD equivalents. A reasonable degree of of major components, does, however, exist between 'common user' vehicles.

Notes on MT Vehicle Model Designations

The following notes are incorporated to assist in the identification of various MT vehicles by reference to the makers' model or type designations.  The designations shown here are relevant to vehicles produced up to the mid 1950s although some may have remained in use beyond point.

The code letters ZS, following the type designation (e.g., K2/ZS), indicate that a GS. lorry body, is fitted. The code letter Y, following the type designation, indicates ambulance bodywork.


Bedford model designations In most instances consist of a letter or letters denoting a basic type and/or the makers' payload rating, in conjunction with the following standard code

S - Short wheelbase
