All the Reliant SV heads I have seen have a large hole at the front nearside for the distributor to fit into.

Scrolling down the page gives a clue !!

Location: in the warm

I'm certain that it's not from a Ford.

Everything apart from the water outlet looks A7.

Location: Herefordshire, with an "E" not a "T".

marine head?

the only clue that gives is that the seller has no idea what it is.

It's certainly not Ford, nor does it fit a Reliant Robin!

The combustion chamber shape suggests early 1930s rather than late 1930s, and it certainly looks like it originated in Longbridge - both in the general shape and in the casting markings; but the Austin Ten, Big Seven and Eight all had the water offtake in the centre of the head, so that leaves ... I haven't a clue!

The cast outlet would be more robust that the standard arrangement. Could it be a military spec?

... but military or marine applications don't explain the different stud layout ...

Not Ford 8or10hp side valve,distributor shaft hole is on nearside,no hole.

I am sure this type of head has been discussed here before. Whilst the general layout is Austin Seven like, the head stud layout differs, note the centre stud is not in line with the others (or visa versa). The centre water transfer hole also looks v large.

I've no idea what it is. Just to note Rosengart unlike other foreign built sevens did not have mirror built engines and were also right hand drive, atleast until the Adler company got involved circa 1936

My guess is that it'll be a 1920 Coventry Climax head. They made lots of engines in that period for 'assemblers'.

I believe it may be a Triumph Super 7 cylinder head

Thanks Ben, mystery solved!

I recall that Stanley Edge told me that he worked briefly on the Triumph after he left Longbridge.
