Federal Sign and signal twin beacon ray model 11 light bar info.
Hey brothers and sisters, looking for some advice. An old teacher of mine was an EMT back in the 60's and 70's and gave me an old light bar. It's an Federal sign and signal Corp Twin Beacon Ray model 11 light bar. It's fully functional and It has a mounted speaker which I believe works. I have no use for it and it is just gathering dust. It being old I feel like it should go to a good home and I posted it on some Firefighting "flea markets" on facebook and received a couple offers of $100 but I was told by numerous people that it's worth more like $400. I tried to look around on ebay and other websites but I can't find any info on prices or what they sold for. So if Anyone can help get me some accurate info on pricing for it I'd appreciate it.
