What would have been the standard radio sets fitted in Stirling of the N60xx range, in June-July 1941 ?

Was the Receiver R3003 standard equipement ?

What was the transmitter ?

What was the use of a "International Marine Radio Company, London" set, type T.G.5.C. ? An emergency radio set similar to the U.S. "Gibson girl", to be used at sea in case of a ditching ?

thanks in advance
