5/05/2012 British Post Offices in Siam
An extremely rare and valuable British Post Office in Bangkok treble "B" overprint variety has been found by a UK collector in a messy old mixed carton lot purchased in a mail bid sale.
The 2c pale rose stamp, listed as SG15c, was found in a mixed lot described as a "Glory Carton" sold by Sandafayre who were then asked to have the stamp expertised.
The stamp dates back to the time when the British Consulate at Bangkok operated an overseas postal system for foreign residents. From 1858 mail was dispatched by steamer to Singapore and then from 1876 it was increasingly franked with Straits Settlements stamps. Initially stamps were cancelled on arrival at Singapore but later a "British Consulate Bangkok" postmark was used and in 1883 after the introduction of the "B" overprinted stamps a circular date stamp was introduced.
"The 2 cent treble overprint was missing from the recently auctioned Indhusophon Collection, considered to be the best and most important collection of Thailand stamps ever sold" says Andrew Morris of Sandafayre, "It's an exciting find and we're sure it will arouse a great deal of interest, particularly as it's not known how many other specimens there are."
The Bangkok "B" 2c variety had an estimate of between £4,000 & £5,000 and was offered for sale in 2001.
