The telegraphUncategorized / By Colin Williamson 70 / 100 Powered by Rank Math SEO This is Explorer’s Siemens Brothers stokehold telegraph. It is a repeater only. In the wheelhouse and on the engine starting platform there were transmit/receive units. Unfortunately during the wilderness years those two units have been pilfered. If anyone knows the whereabouts of replacement units, the society would be delighted to hear from you.
