Original British Army radio equipment probably from the 1950s, 'CASE CARRYING ANTENNAE RODS NO. 5' 'Z.A. 2S120'. There is also a stamp showing the manufacturer but that is difficult to read. The item is in very good condition.
A print-out is included from the User Handbook for Wireless Set No. 31 (Manpack) Mks. 1 & 2 1957 that has a photograph of a soldier wearing a wireless set and its accessories, and a diagram, so you can see what the case looks like in action.
