Well spotted…so that tunnel was there from the beginning of the Central Area, and it looks like the 1960s Cargo Tunnel perhaps used some of its path

Uploaded for Rosevidney1 …looks like a one-piece sand casting to me so a wooden pattern would have been made to produce the sand mould ? [ATTACH=CONFIG]260509[/ATTACH] [ATTACH=CONFIG]260506[/ATTACH] [ATTACH=CONFIG]260507[/ATTACH] [ATTACH=CONFIG]260510[/ATTACH] [ATTACH=CONFIG]260508[/ATTACH]

Very nice find, Lazy8….It overlaps a little with some recent reading of mine about 232 Squadron operations from Ceylon in 1945/1946 (Liberator, Skymaster transports.) They used service codes LA (Liberator) for Delhi-Ceylon (daily each way), LY (Liberator) ( Ceylon-Cocos Isl. (weekly each way), LV (Liberator) Ceylon-Cocos Isl.-Guildford, Australia (twice weekly each way), LZ (Skymaster) Ceylon-Cocos Isl. -Guildford-Sydney, Australia (thrice weekly each way). These seem to be service codes rather than route codes like UC and U.I.C, though. Perhaps a route information book was produced for the Ceylon to Australia service…that would be a find!

Did Cierva patent their ‘NOTAR’ jet torque compensator system?

This was presumably produced around the end of the war when RAF Transport Command was effectively running an airline (to the detriment of BOAC ), both ways round the world to Australia with Skymasters and Liberators (C-87s and single-fin RY-3s)….would be nice to see it scanned on the net but the cover alone is interesting ( what do the route codes UC to UIC mean?)

The post-war tents were at Heathrow some 3 miles from Heston Aerodrome a completely separate airfield which was still active until 1948 (and later :-))

Very publicly spirited of the ebay dealer! 🙂
