My Father was in the Royal Corps Of Singnals from around 1960 to 1970 and I am working on some family history regarding him, his father and grandfather who all served in the army. I have identified the correct cap badge for my Dad and these are widely available, but I am trying to find out whether he would have worn a trade badge and what it looked like so I can have a better chance of finding one. He was a Radio Relay Technician and I seem to have found some contradicting info - either a cloth sleeve badge was worn or metal crossed flags but I favour the cloth badge as I know there were several distinct trades which I would think would have their own identity. Any help would be gratefully received.
