The previous latest recorded date for F.P.O 1 was Christmas day 1918 when located at Limbe; this later date suggests the F.P.O may have then moved to Zomba, possibly the site of a demobilisation and transit camp. A scarce and intriguing card. Photo on Page 182. (Image1)

F.P.O 2 at Rungwe. 1916 (Sep 20) Stampless O.H.M.S cover endorsed by "J. Stuart, Masikulu", sent from New Langenburg with "F.P.O / 1" c.d.s to "Lieut Miloma, Mseswe via Rungwe", backstamped at Rungwe with violet "F.P.O / 2" (Sep 22). F.P.O 2 only used at Rungwe from September 21st until November 15th with all known strikes in violet, this cover described by Pennycuick proving its place of use. Very few commercial covers are known and most cancels are faint and unclear.

This FF2 squared circle is recorded used at Likuyu from August 14th 1917, but at least seven covers all self-addressed by L.H Rivers are known with the cancel dated May 19th; Pennycuick suggest these May covers are fakes produced by Rivers using the genuine squared circle, then in use at FF5, with the FF number altered. An interesting cover.

F.P.O 2 at Mtangula, Portuguese East Africa. 1918 (Mar 9) Stampless O.A.S cover to Scotland endorsed "From J.C Rhynas No 218 B. Coy L.G, B.S.A.P" and countersigned with "NYASALAND / FF2" squared circle, various repaired edge tears at edges and piece missing at upper left corner, but an exceptionally rare commercial use. F.P.O 2 at Mtangula is recorded on about six covers bearing Portuguese Nyassa stamps all of which have clearly been cancelled by favour and have not passed through the post, and on just three commercial covers, one of which has a large portion torn away.
