8 port X Flow head - Small Bore

Hi All.
I was wondering if anyone can shed any light on this lovely little cylinder head?
I acquired it many years ago when I got a MOWOG and Weslake from an Ex Experimental Dept engineer.
I am interested to sell it as I only have large bore engines but would love to know its origin as a prototype or the like.

Warm Regards Ben

It looks very similar to one I had years ago. I am not at all sure that it is for a small bore engine though, big valves, even spacing, 11 studs, all point to it being for a large bore.

Do you have any better pictures?

Is there a solid steel plate cast into the head that acts as the valve seats & chamber skull?

Thanks for the replies all.
I will sit it on a 1275 block as it may well be large bore.
Does anyone know its possible maker?

I will measure valve sizes and post.

Also I tried to reply to couple of emails via MK1 perf but they bounced.
My email address is ben_tebbutt@hotmail.com
