Great Britain #586, 596a, 597a 1/6d Grey Blue Wilding & 5/- & 10/- Bradbury Wilkinson Castles, Combination Use on a Telegram to Bombay, India
A fine Radiotelegram sent to Bombay India on January 21, 1965. Franked with 1/6d Grey Blue Wilding and 5/- brownish red and 10/- deep ultramarine Castles, paying the transmission rate of 16/6d for 1 chargeable word. The message "Christopher has no intimation (indicaton)". Is very cryptic and suggests this was part of an ongoing conversation.
A fascinating piece of history that shows just how far communications have come in less than 60 years. A read of the conditions on the back reveals that senders had to wait 5 hours in some cases before their message was transmitted. This is the days before international long-distance calling was standard and at the time is was very expensive, as the Commonwealth Pacific-Atlantic telephone cable had been installed only a few years earlier. There is a vertical file fold unfortunately that affects the 10/- castle stamp, but the condition overall is still fine.
