Solas Radio transmitter receiver
Something that most of us hope we'll never see let alone use I guess! Early Sailor SOLAS emergency lifeboat radio.
500Khz, 2182Khz or 8500Khz AM, a strap for round the waist, a foot strap & 2 crank handles fit in either end, then crank the thing to turn the internal dynamo and power it up. Aerial was a bit of wire, earth was another bit of wire with a lead weight that you chucked over the side.
I've gone a bit anoraky with old radios! found this one, and after a bit of fiddling the thing works fine!
