Cockpit Lighting

Hi all

Not sure if anyone can help, but I’m trying to identify the 2 spotlights as fitted to the coupe roof on the Stirling. I’ve looked at Air Ministry’s guide to electrical equipment and have guessed that they might be 5C/793 spotlights with a conical shade/reflector. If someone can confirm my supposition and/or point me in the right direction for some example with that type of shade I’d be very grateful

regards
