Engine number:
The GTS has an engine prefix of “12H-GTS-H”, followed by a 4 digit unique engine number. This prefix and number is reverse stamped on an aluminium plate riveted to the engine block as demonstrated in the images. The 4 digit engine number is also stamped into the engine block face just above the oil filter, below the head, and should match the unique engine number on the engine tag.57
Engine block and head characteristics:
The GTS received a 1275cc engine of very similar specification to the Cooper S. The block was locally cast in South Africa by Gearings Foundry in Epping, Cape Town - using the British-spec MK2 Cooper S engine as a template.58 This local production contributed to the GTS achieving local content benchmarks to reduce taxation duties.59 The decision to build these engines also meant that South Africa became the only country to continue using a Cooper S spec engine block through the 1970s, whilst elsewhere that motor was phased out and replaced by the rationalised 1275cc motors with a solid rear block wall (for example, that used in the 1275 GT). The closest factory built engine of the era in terms of power was that applied to the Innocenti Mini (1300 Export).60 This used a 1300 GT engine and several Cooper S accessories such as twin SU carburettors, and was built up to 1975. This was still down in power terms at 70bhp, vs the 74bhp of the GTS.61
Like the Cooper S, the GTS engine was an 11-stud unit, had integral side covers and the head received double valve springs. The head had an inlet valve diameter of 35.65mm, and an exhaust valve diameter of 29.37mm. The block was bored to the same specifications as the Cooper S, with a 70.64mm bore, and a stroke of 81.33mm to achieve the 1275cc. The compression ratio was also 9.75:1. Unique to the South African engines, however, was the location of the oil filter gallery, which meant the oil filter was fitted above the starter motor. Despite the similar specifications, the GTS produced 74bhp, (slightly down on the original Cooper S).
Engine blocks and heads were finished in a semi-gloss grey/black paint. We have not yet been able to confirm the paint code. For additional performance figures and mechanical specifications of the GTS engine, see section 6 of this guide below.62

This very original Mustang was advertised on Ebay USA, with a buy it now price of $6,800 USD. This is what is referred to as a 1964 and a half model (being a Mustang car that was built before August of 1964). The Rangoon Red paint might even be its original - looks faded, and along with its surface rusted chrome, the car would really make a great Patina style finish.
