Only One Available. This is a genuine Vietnam War M1 Helmet with a camouflage cover and an attached issue AN\/PRR-9 radio receiver offered in very good condition. The radio has not been tested for functionality but appears complete and undamaged. These receivers were intended to work with the PRT-4 squad radio transmitter. They were intended to replace the bulky PRC-6, which had been in use since the Korean war. Also included is a transmitter AN\/PRT-4A which is carried in the hand or on the belt. It is missing the battery. This is a very difficult set to find together.\u003c\/p\u003e\n\u003cp\u003eVietnam War era M-1 helmet shells have a set of swivel (movable) chinstrap loops called bales and a stainless steel rim. These rims were both rust resistant and had non-magnetic qualities that reduced the chance of error readings when placed around certain sensitive equipment (such as a compass).\u003c\/p\u003e\n\u003cp\u003eThis helmet is a fine example and still retains all of its original Vietnam War parts and the shell has all original corked grain paint.\u003c\/p\u003e\n\u003cp\u003eThe liner is a correct high pressure 1960s issue liner. The rigging is intact and in great shape, with a nice leather sweatband. The cover is original and in very good condition. It has some stains and small holes around the edge, but is definitely solid. The cover is unmarked that we can find.\u003c\/p\u003e\n\u003cp\u003eThe data plate on the radio receiving set is either gone or out of view, so we cannot read it. The antenna is also missing on this example, but it still displays well. \u003c\/p\u003e\n\u003cp\u003eThe data plate on the radio transmitting set reads\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eTRANSMITTING SET, RADIO AN\/PRT-4\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eSERIAL NO. 24581\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eDELCO RADIO DIV, G.M.C.\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eORDER NO.
