[TR] Identifying Spitfire Cylinder head # TKC 2748

[Wayne Lee]

I have a Cylinder Head that came with the 69 Spitfire Mk III I bought.
The Stamped # is TKC 2748, Casting #'s are (RKO 0589) and (V3315 2840)
Maybe the Casting #'s can be off a # or so, I swiped them with some Emery 
Cloth
but still not clearly legible.

The Intake Valves look to be about 1.380" and it does have Brass Plugs in 
the Air Ports
above the Exhaust ports. I'd say it's definitely a 1500, but I'd like to 
know what year.

Any help would be greatly appreciated.

Cheers,
Wayne Lee
