A New "Last-Recorded-Date"
I found this stamp online and paid 5p for it. It's Straits Settlements SG225, postmarked with Prye (Prai), Penang, Proud type D3.
Proud's "The Postal History of Malaya Vol 1" states that the recorded dates for type D3 were 6 December 1917 to 23 January 1925. Although the month is unclear, the left leg of an "A" is evident, meaning this was postmarked 27 April or 27 August 1925.
I sent an email to Proud Bailey, and received a very quick reply from Edward Proud, confirming that this is a new last-recorded-date, and stating that the next edition will be updated.
I'm fascinated that finds like this can be made 87 years after the event!
These are the little things that make our hobby so intriguing and worthwhile.
