Updated!!! I am compiling a list of the voyages of the HAPAG ships between Hamburg and New York. So far I have finished the years 1869 to 1878 and they are available for download here: Voyages HAPAG, Hamburg - New York 1869 - 1878

New Covers in "Canal Zone RPO". And a new topic under "Canal Zone" - "Fort DeLesseps".

I am looking for scans of postmark strikes

I am looking for scans of postmark strikes of the " N.Y. & CANAL ZONE" Seapost. It is about this one:

Since the literature on this postmark is not informative enough for me, I would like to try to bring "some light into the dark".
Please email them to this address: jkuseler(at)wtnet.de

300 dpi would be good. And thanks for the efforts!

Hello! Nice that you have found to my homepage! I think that you are probably interested in philately, since this is in the domain. Then you are right here.

As you will quickly notice (almost) everything revolves around the USA. A large part around the sea posts (until 1941) and around the Canal Zone. An exception is the HAPAG. If you disregard the "Deutsch Amerikanische Seepost/US German Seapost", in which it was involved.

But it all started with HAPAG - I'm a citizen of Hamburg - and that was followed by the "US German Seapost". After some time I extended that to all US Seaposts. And a greater interest in the Canal Zone developed.

If you click through here, you will, I hope, discover one or the other interesting thing.
I hope you will enjoy it!


A cover posted and postmarked aboard ship at an official post office of the "U.S. SEA POST SERVICE".

This postmark is from the second sea post line on the Pacific, from San Francisco via Honolulu, Kobe, Shanghai, Hong Kong to Manila. These postmarks can be identified by the letters "SF" in the CDS. They were used only in 1924 and 1925, beginning on 05 Jan 1924. They had numbers from 15 to 23, each of which was permanently assigned to a ship.

As the indicator "WEST" says, cancelled on the voyage from San Francisco to Manila - on 26. July 1924 - postmark with the number "17". Addressed to "Arc-en-Ballois", France. On the reverse the arrival postmark from there dated 18. August 1924.

An envelope like those freely displayed in 1st class cabins on many shipping lines. The ship name, here "PRESIDENT POLK", does not guarantee that this letter was postmarked on this ship. From the "PRESIDENT POLK" this is my second letter. Both with different numbers.

Much about this stamp has not yet been definitively clarified and is subject to its own research.
