My dear cousin has donated me her late fathers old suitcase of his national service memorabilia, as she is terminally ill and knows I will treasure his belongings. He was in the Royal Signals and there 4 items I am unsure of and would like your help. The first two items are insignias of some sort and the next 2 items are what seems to be a container with a measuring "spoon". It is 3 3/4 inches long. The lid/spoon has a seal, (I suppose to keep its contents dry, or its contents leaking?) and also what seems to be a thimble but with no 'end' on it. Could it be something used for sending morse? Its been great looking through his old things. His Exercise books, letters from home, signal training pamphlets etc. My own father discarded all his national service stuff, whereas my uncle seems to have made off with half the barracks! Thanks in advance. Ivan
