WORKS 1978-79 StarForce Gor helmet, W/ Box, Chin strap, + instructions, RARE OBO For Sale

REALLY RARE 1978-79 Kingsford StarForce Gor helmet, With Box, Chin strap, and instructions. The microphone does still work, with a 9-volt battery. Though not completely clear you can make sounds through it.I have only found two listings on before.
One sold listing was $120 that was just the helmet.
The other is a listing still up, for $200 that\'s also just the helmet.This product I\'m trying to sell is negotiable because I don\'t know what price to put on it with having all of it parts but the yellow visor and working.
