Production Facts & Feature Time-lines

These pages contain production numbers, dates and the time-line for various changes to the MGTD during it's production run.

The MGTD Models

There were three models of MGTD during production but only two are really discernible. Those were the TD, TD2, and the TD Mark II. The TD2 was just an evolution of the TD while the TD Mark II actually added additional features, a unique identification, and simultaneous production with both TD and TD2 cars.

Production Facts

Total production for the MGTD was 29,664 of which at least 1710 were TD Mark II's.

¹ It would appear that of the 103 LHD chassis exported during 1952 and 1953, all but three of these were Arnolt MG's that were sold in the US. Total production for Arnolt MG's was 102 cars, two of these were the prototypes that were created in Italy with used chassis from production cars.

²CKD - "completely knocked down". A term used to describe cars that were exported in kit form to be assembled "in country". This was sometimes used to claim that the cars were manufactured locally to get by import tax situations. Cars were finished in primer only. To get an idea how CKD cars were utilized check out this web site about the BMC in Sydney, Australia.

Car or Chassis Number Codes

The following table illustrates the car number coding scheme for the MGTD. These were documented on a stamped metal plate on the cars left hand firewall. In addition each car received a unique number starting with 0251 and ending in 29915.

Code Description
TD³ All MGTD's except for the competition or Mark II models
TD/C³ Mark II or Competition models.
EXU Export, United States (early version)
EXR Export - Right Hand Drive - MPH Speedo
EXRK Export - Right Hand Drive - Kilo Speedo
EXL Export - Left Hand Drive - MPH Speedo
EXLK Export - Left Hand Drive - Kilo Speedo
EXLNA Export Left North America
EXRNA Export Left North America, Right (most often intended for racing?)
EXLM/FL Finland?
EXL/FL Finland?

³ The TD always preceded the code. For example, a later North American, exported, left hand drive regular MGTD would be coded: TD EXL/NA.

Additional code information supplied by Tom Lange.

Engine Number Codes

All MGTD engines were marked as XPAG. The following table illustrates the additonal engine number coding scheme for the MGTD XPAG engines. There was no absolute correlation from the chassis or car number but the engine number was generally about 300 - 350 or more larger. The engine number was stamped on the metal chassis plate, on its own octagonal plate on the right bottom front side of the engine and just above this plate, on the block itself.

Code Description
TD Engines prior to 14xxx with 7" clutches
TD2 Engines after 14xxx with 8" clutches
TD3 TD/C or Mark II engines after 17xxx

Production Dates

Production date timelines from M.G. Talk, the South-Eastern T-Register’s Newsletter. First number is day of month, second is the first or last serial number car for that date. This should help you in determining the actual age of your car. You might also want to get a copy of the factory log book for the date of your car from the source mentioned here. There is an online tool available from the T Register T Type Factory Production Records.

Feature Time-lines

Over the product run of the MGTD various changes, while mostly minor, where made. The following table attempts to chronologize some of the notable externally visible changes by date and/or chassis number when known. (e) stands for engine number.

Note: The production feature time-line presented here is derived mostly from manuals, brochures and a few factory records by Anders Clausager. The dates should not be considered absolute. In fact many cars have been shown to exhibit an earlier trait far beyond the date shown as having a new feature. It is believed that these dates comprise the first time a new feature appeared on the MGTD, rather than the last time the former feature could be found. At times a decision seemed to be made to change a feature in one marketplace while still producing the former feature for other marketplaces. Note also that the MGTC was still in production when the first MGTD's appeared. Also note that during the production of the MGTD that other cars were still produced on the line at the same time. It may have been that cars produced during those periods would use similar parts while during the times that only MGTD's were produced, a different, but similar part would be used .

Note: MGTD's were one of the last cars manufactured by Nuffield prior to the change over when incorporated with BMC. Up to that point few records on individual cars were kept and the production information is not as complete as on even the MGTF and later models. The information quoted in the Feature Timeline section is the best there is available but cannot be considered absolute. There may have been exceptions to this data. See the Noted Exceptions to Production Data pages for more information or to report a discrepancy.

¹ Earlier engines were not specially marked; later engines were marked TD3.

Much of the above was used with permission from Original MG T Series by Anders Clausager. Published by MBI Publishing Company 1-800-826-6600.

Note: At some point in production both Girling and Armstrong shocks were used. The Armstrong shocks required a small raised area on the front fender to allow for their higher clearance. This bulge does not indicate that a particular car had Armstrong shocks, but rather that the fenders at that time could accommodate either shock type.

TD Mark II Features

Almost immediately when the MGTD appeared on the market there existed a strong aftermarket of parts and accessories to increase the performance and sportability of the model. The Mark II MGTD, in later years called the TDC, was an attempt by the factory to satisfy the demand for more high performance models.

Parts List of Mark II Features

Almost all of the Mark II items were available separately during the production of the TD,and are listed in the Service Parts book.

²The hood and bumper emblems were the same. The bumper emblem was mounted on a special plinth.

An image of some of the Mark II parts from the service and parts manual can be viewed here.

Note: Almost all of the Mark II items were available separately during the production of the TD.

A few comments on the Mark II by Thomas Lange

All Mark II's had the bonnet bulge because early cars used a 1-1/4" TD air intake and oil bath filter, with the 1-1/2" carb flange mounting holes filed inward into slots to accomodate the narrow bolt pattern of the smaller air intake (early photos sometimes show these slots). Later cars used the unique enlarged air intake with hole spacing to fit the 1-1/2" carbs, so filing was not necessary (from 22613?). These later cars also used the larger oil-bath filter. The bonnet bulge was necessary for both air intakes.

There is no evidence to suggest that Mark II's came from the factory with Vokes filters as found on TF's, chrome (aftermarket) pancake filters (as usually seen today on cars being driven), or with no filters at all (as often shown without comment in contemporary road test photos, presumably to improve breathing).

Factory Accessories

While the MG factory had very few accessories for the MGTD, there was no shortage from aftermarket companies. The following is a list of the factory accessories during the production run of the MGTD.

Note: Wire wheels were never offered by the factory during the production the the MGTD. They were available later as a service kit, part number ACG 5163 (5162?). These were essentially the parts used by the TF's that would also fit the TD's. There is also a slight difference in the '54 wire wheels from the '55 wire wheels. The '54 wire wheels inner hub was more pointed in shape, similar to the shape of the original dash finish washers, while the later wire wheels found on the '55 model TF had a more rounded hub common on MGA's and later cars.

Carl Cedarstrand of the Vintage MG Club of Southern California wrote an article about wire wheels on a TD for the June, 1979 issue of The Sacred Octagon. Carl discovered a factory part number for the TD spare wheel carrier - ACG 5162. The part number was confirmed by Mr. Pete Neal at the MG drafting office. Mr. Neal also advised that the part number was taken out on November 4, 1953 which Carl points out was almost 2 months after TD production ended. Carl goes on to say that is very unlikely that a wire wheel TD was ever produced by the factory, but that a TD could be retrofitted using all factory parts. A proof of this was an advertisement in March of 1954 for the TD Wire Wheel Conversion kit from Gough Industries, the MG Importer in Los Angeles. The kits used all factory authorized parts admittingly from the production of the MGTF.
