Was at a sale recently and there was a tin trunk full of letters, papers and photos relating to an officer of the Scottish Rifles (IIRC) who was at Gallipoli. Letters were address "M.E.F.": Mediterranean Expeditionary Force. The trunk wasn't for sale, but was left in an insecure location, which I remedied. I suggested they get it all scanned. The stuff is still out there. One of my great aunts was a nurse at Salonika. Zeppelin bits she brought back used to adorn the grandparent's mantelpiece!
