Help identifying this engine

[Matthew Reid]

It is a BMC A series engine. Most commonly used in the Austin Mini.
This one is likly from a rear drive application such as an Austin Healy as it does not have the sump mounted gear box.
BMC owned a plant in Belgium that made cars and engines.
The OD green is a factory painted colour on these engines.
