Help identifying this engine

[Richard Farrant]

Bob,

BMC (British Motor Corporation) engines were generally from the parentage of Austin or Morris. If this engine has a crank handle facility, then that dates it back a bit. From what you say it is on a frame with radiator, so sounds like a power unit for something other than a vehicle. You also said that it had "BMC" on the valve covers (plural), was that a slip, or does it have separate valve covers? If so then doubtful it is BMC as above, also being "made in Belgium" does not sound like the above. A picture will speak a thousand words, so awaiting it eagerly!
