This is an engine from a New Zealand assemebled mk4 1275GT.
The car it came out of was first registered in 1980 but since around 1990 it has spent its time in a mk3 1972 Mini 1000.
As far as I can tell this particular engine is a mish mash of parts, including an a-series block with a some a+ series gearbox parts.
