Supermarine Spifire Prototype K5054

[jerryw]

Does anyone have a copy of the report:

Aircraft Armament Experimental Establishment - Martlesham Heath
July 1936
No. M 4493/20
"Report on Spitfire K5054"

This report should give the ENGINE NUMBERS of the R-R motor. There should be two serial numbers:
1/ The R-R No "C 5,7" etc and
2/ The Air Ministry No "A +six figures."

Thanks,
Jerry.
