This is the UK made IMR Solas. Hand cranked it could transmit and receive on on 500khz and 8364 khz. This was one of the few lifeboat sets that could actually transmit voice on 8364 just in case there was no RO available.
I do recall the apochrophal tale of a certain lifeboat radio being tossed over the side from a ship in Liverpool to test its floating qualities..... the securing rope broke or hadnt been properly secured and it disappeared like a stone!!.
Suppose this is on board Shell\'s tanker Naticina?
I remember having been on board several times in the late 60\'s, used to come to Rotterdam.
However, I think I also have seen it built in Lindo Shipyard, got that special one coat Galvosil (zinc silicate) on the maindecks.
Would not this "Naticina" be the wartime built vessel which was one of the Shell twelves? 12,000 DWT, 12 knots, 12 tons of fuel per day. Some were also I believe converted to MAC ships, merchant aircraft carriers, towards the end of the war.
Sisters were the Tyne built "Neverita" and "Navicella"
