Morning from Lagos;
FINALLY!
Hexcode 500060 is T7-KAS, looks to be a legacy. With some judicious twiddling of me knobs on my scanner, I managed to catch him calling his reg upon landing. Callsign was "Skylark 4207X" and 3 letter code was given as "LRK". It is not in my Db....or yours Alan, I think we use the same one! Any confirmation of the type would be good.
regards clive.
