Stamped cylinder head identification please!

[AustinSuperSeven]

Hello everyone.
I've got an 11 stud 12g940 head that has been nicely worked.
At the heater tap end there are some numbers and letters stamped.
Letters are OES FR and numbers are 11-1 (compression ratio?).
Are these company modification marks?
Any help would be appreciated.
Regards
George

I think I might have just answered my own question!

Oselli began as Oxford Engine Services (OES) in 1962. It specialised in the tuning and enhancing the performance of MG Rover/BMC products. Initially improving the performance of the Mini by way of porting and flowing of cylinder heads, fitting large valve heads and then increasing engine capacity.

I'm assuming the FR would be the initials of the person who worker the head.

FR - Fast Road?

FR - Fast Road?

That's a good one, and makes sense.

It's me again!
Spoken to Oselli today and they have confirmed it is one of their heads and the FR does stand for Fast Road (well done 1071kev).
I've got the complete engine this head came off, as well as the twin h4,s! Blyton park here we come.....
