A MOCK UP OF A 1940'S SHIP RADIO ROOM AT A MARCONI  EXHIBITION. ON THE FAR LEFT IS THE MARCONI AUTO ALARM RECEIVER TYPE 'M'. NEXT TO IT IS THE GONIOMETER FOR THE DIRECTION FINDER RECEIVER SITING TO ITS RIGHT - THE MARCONI TYPE 579. THE R/O IS TUNING THE 500 WATT M.F TRANSMITTER TYPE 381.THE RECEIVER JUST BEHIND AND TO THE LEFT OF THE R/O IS THE MARCONI 352A RECEIVER. HIS LEFT HAND IS RESTING ON ANOTHER TRANSMITTER, PROBABLY AN H.F TRANSMITTER, BUT I CANNOT IDENTIFY IT. FOR MORE DETAILS ABOUT THIS EARLIER MARCONI RADIO EQUIPMENT TAKE A LOOK AT THE 1930 - 1950 SECTION.
