I just can't see what food container would fit into it. Certainly nothing that I have come across and I used '37 patt webbing in the early to mid 60's although to be fair, tyhis was just the basic stuff. The pack certainly looks partially insulated where it contacts your back but the pack seems too shallow to take what we currently call a 'Norweigan' - even a smaller 'pudding Norweigan'.

Hot food.......... I came too in hospital after an emergency op on my knee after being dragged along when a parachute wouldn't deflate. The bloke from the Devon and Dorsets (known as the Devon and Doughnuts) in the bed next to me was recovering from severe burns to his legs and 2 bullet woulnd from a .45. His Land Rover had been taking dixies of hot food out to a RV point and had come under IRA ambush fire. Hit him and the driver and turned the L-R over. The dixies split open scalding the blokes badly
