Too late for Dad, who served in HMS KGV as a Signal Boy, aged 17. He remembered an oerlikon gunner who froze to death at his post because the "black heater" in his sponson had failed. And being sent up the mast and out along the yard arm to free a signal flag that he had got jammed in the block. In a force eight, 20 below and rolling 15 degrees either side. It was a different life. May God Bless them all - nobody else did.
