This Appliance did indeed start off in Aberdeen then was transferred to Oldmeldrum Retained Station about 15 miles North West of Aberdeen followed by a stint at Gordonstoun Boarding School where Grampian have a Volunteer Station.
There's a 15 min video on Youtube about the Volunteer unit at Gordonston called "November 39" takes a while to get going, I'm not sure if the appliance is shown in the video but it's sister VSA635L is.

This was a D1013 with the Ford six litre 130 BHP diesel engine, which was pretty much a standard commercial offering in the D series product range. Other versions were the SVO 1014 (five litre turbo diesel), the SVO 1317 and standard 1617, both of which had the Perkins V8 eight litre engine.
Some 1414 were also built for Australia and New Zealand fire appliance applications, and other lighter commercial D series chassis were often used for a variety of ancillary and support special purpose units like BA, ICU, hazmat tender and similar roles.
Simon: This takes me back to the very first eleven D600 HCB Angus appliances, which we supplied to Gloucestershire in 1967. Several of these are portrayed in photos on this site.
Although the brigade already had at least one diesel - I think it was an AEC aerial - they still wanted petrol power. So SVO built these with a five liter Ford of Canada petrol engine, which was only offered on fire appliance chassis. It was quite powerful, but also very thirsty!
The petrol engined build was apparently still available in 1973, when this unit was built, but by then almost all brigades were switching to diesel power, and many wanted the 170 BHP Perkins V8 which SVO engineers had by then squeezed into the 13 ton chassis.
By the time this unit was built, HCB Angus had also greatly improved the appearance of these appliances, with a much better integration of the standard tilting factory cab with the rear crew cab and bodywork.
