Restored and displayed Federal Sign and Signal EG Siren. This beauty was manufactured in May 1958. It was a little rough when I picked it up but cleanup up nicely.
It's a rarity to see one of these. I've been trying to get some historical information on one I received years ago as scrap. May I ask how you found your manufacturing date. I have the 12 Volt Model EG with a Serial No. 2L12A8.
There is only one wire coming out of the housing. That is your positive. The ground is through the base. If you are doing a static display you will have to run a ground to one of the bolts on the base.
Prices vary. I rarely spend more than $100 for any of my stuff. I am patient and wait on deals. Best guide that is free is to do an Advanced Search on Ebay and select "Sold" to see what they sold for vs the outrageous asking prices you see on Ebay. What they sold for is the only true source.
