if there is anyway you can test them they would go for about $15used in good shape but if the entire thing is there and good that's a good score but a lot of shipping as you would need to break it all down and pack in cases and ship it but if its good I would start it at about $450 with free shipping but at $50 it will sell but may take a few for people to look for it.
even non working I would have capped the ends and dummied the wire leads so it would be safer and sold it as a prop for $100 plus shipping
