Not seen those Lindner Album Pages before.
The pages are Lindner T Blanko. In this case it is product nr. 802502 as you can see below the Lindner T logo. Pages cost close to € 4 and come in packs of 10. The background to the stamps is my own work, using MS Word and a printer. The product code for this particular inlay is 802001. They also exist in black and other formats. There are a few wider pockets in the Lindner T Blanko range.
I suspect the MEF ran the postal service for the islands until they officially became part of Greece (and probably in close co-operation with Greece).
I think that is correct. The M.E.F. stamps remained in use on the Dodecanese Islands until the end of the occupation in 1947. Most of the other former Italian territories introduced stamps inscribed with the name of the territory from 1948.
Were there Italians in MEF?
The Middle East Forces' theatre of operations included former Italian colonies such as the Dodecanese Islands. Italians lived in their colonies. Many left after the allied forces defeated the Italians, but some remained. Some territories, officially, were Italian colonies until 1947. As such, they were under British or sometimes French occupation. From 1947, the territories were run by a British Military Administration (B.M.A.) until they became independent or united with another country.
