?Cackleberry (negat crackle..). Whistleberries per contra being baked nbeans. Always understood that train smash was tinned tomatoes. Herrings In were always Herrings In. Supplied (like Corned Dog and ship's biscuits) as emergency rations, which had to be rotated to keep in date, so tended to turn up rather regularly. The corned dog was in 56lb tins so rather a problem in a minesweeper to get through a tin in one sititng as it were.
Banjo = filled roll (any one know where this one comes from???)
I have always taken it from Egg Banjo where after completion you always find egg yolk down your front and attempt to wipe if off. The wiping motion being akin to playing a Banjo, well thats what my sea dad told me!
