Default Re: Any information on this US Navy receiver please?

Thanks for all the replies, the link to the document provided by Stockden gives information on the receiver type RAY which appears to be an earlier version of the RAY-5, the valves (tubes) used in the RAY-5 are different, the line up is 12SR7,12J5, 12SN7 (2),12H6, 6AC7, 6AB7 (3), 12A8G, the RAY-5 taking advantage of the availability of higher gm valves.
The unit appears to be of wartime construction (the contract date is 44) as cloth covered wiring is used throughout, no pvc.
I would be grateful for any leads for obtaining circuit information on this set.
Mike.
