That's a NSW police issued number, so it won't tell you what it is. Does the back of the block have cover plates or not?

Lots of minis that have had a 1275 transplant are using the 1100S engine (12YD engine number).
These have a 12G1279 casing number at the rear. This casing was also used in the UK 1275GT.
You used to be able to pickup an 1100S car for next to nothing.

Whenever you bought a NEW (non S) block from BMC (I bought 2) they came with NO engine number.
You took it and the receipt to your local fuzz, they allocated a number and directed you to a business of their choosing to get it stamped.

They `may' also have allocated a Police number if the original was machined off and could not be discovered (a maybe).

Code N (for NSW) 79 (year) 3729 (sequential number that year) P (Police).
