Great Britain 1871 London to Belize via LAMB & CO St. Thomas VI Stampless FL

Stampless folded letter, with contents dated 27 April and endorsed "p. W India Pk to St. Thomas", handstamped on front and back with oval anchor mark of the Forwarding Agents Lamb & Co of St. Thomas, Virgin Islands, rated "4" in blue indicating the inter-island rate from St. Thomas to Belize, with Belize c.d.s. receiver (MY 30) struck on front, light yellowing from climatic influence, else a fine and scarce letter. The contents include interesting remarks regarding mail contracts, with the sender writing in favour of a route via New Orleans instead of the route via Jamaica - "I know it to be the quickest and the cheapest." Ultimately, however, in 1872 the RMSP contract was renewed when a monthly service was entered into between Belize and Jamaica
