Neon bulbs are shattered. Paint is worn. Letters "e" and "r" are broken off. Sign believed to be made of brass or cast aluminum. The sign also has some kind of hooks on both sides of the canister in the back. there is also a stand. surface rust. The cylinder piece on the back has a sticker that says jefferson electrics the plate is a little scratched up but I was able to make out the CAT NO. 723-351 and also primary is 425 volts secondary is 7.500. I'm not sure if that is %100 correct.
