I have picked up the following rather ragged cover, mailed in February 1918, from the "Frühere Kaiserlich Deutsche Postverwaltung" ("Former Imperial German Postal Administration") in Windhoek to Outjo and bearing the rubber-stamp marking "On Service of Late Postal Administration".
As the last German forces in Southwest Africa surrendered in July of 1915, I was rather surprised to find that the German postal administration was still somewhat operating there in some sense in 1918. Can anyone tell me just what they were doing at that time? Presumably wrapping up their operations, but I would have thought that they would have finished that by 1918.

Interestingly, the recipient of that letter reversed the envelope and sent it back later in July 1918. In this case, the marking "On Service of Late Postal Administration" was handwritten.
