POSTAL HISTORY: 1961 (May 11) commercial airmail cover with British Phosphate Commissioners imprint on the flap scored-through, to Switzerland with very scarce solo franking of 2/6d Buada Lagoon (3d convenience overpayment). At the time, the rate to Latin America & the West Indies, no example of which we have seen, was 2/6d. There was no 1/3d rate so this is the only other way to acquire a non-philatelic 2/6d solo franking on a letter.
