The postal stationery is a Hong Kong Registered Envelope "Size F" (3-1/4 x 5-1/4 inches) embossed with King George V 10c in violet. On reverse, it bears the printed 'Acknowledge fee of 10c and insurance sum in Francs and insurance fee in Hong Kong currency from 25c to $2.50'. Thus, I trust it is Webb Type No.7 (p.163). A GB King George V 2d orange was added to the front (probably by the sender) and the embossed HK stamp 10c were all cancelled oval London Registered datestamp with index "7" above the date 2 MR 21. A further oval Registered Nottingham datestamp was struck across the right side of HK 10c violet embossed which indicated arrival, dated also 2 MR 21. A London I.S. registration label in blue and numbered 2666 was added thereon, manuscript "282".

Mr. Neill Granger of Spink, London "……that the letter was from HMS Hawkins, China Station. British stamps were supplied to members on board for posting letters home. The letter would be placed in a ship's bag and processed back in England, hence the British cancellations. A picture postcard lot 1100 featuring this ship taken from the Far East tour was available at the 25 November 2000 Spink, HK auction".

I fully concur to Spink / Mr. Neill Granger's saying that it was originated from HMS Hawkins, China Station. The left bottom sender information, although damaged, still reveals right part of "M", "Hawkins" and also "Station". It was then for sure a correspondence from naval personnel on the board ship HMS Hawkins. London GPO accepted such mixed usage of HK and GB stamps for posting a registered mail by board ship members.
