Vintage set of Walkie Talkies (Hayes UB3)

A vintage 1990's set of handheld Walkie Talkies. This set comes with 2 transceivers and their cases, 2 old style ear phones and one wrist strap all in the original box. They each need a 9v PP3 battery (not supplied) to work and having tested them, I can confirm they still work. There is a picture showing the spec which shows that they only operate over a short distance i.e. 1-2 km so these will probably be just for a bit of fun.
