My father served with the Counter Mortar Organisation 10th Indian Division. According to the CMO war diary - Castagnavizza 12 June 1945 The CMO visited an exposition of photographs dealing with the exploits of (Kostanjevica 10th Indian Division Slovenia) There is no other comment and I wonder what happened to the photos.
