Here is an item I'm willing to let go of that could be considered an insulator go with. It's a table lamp that is, I believe, from the 1970's or early 1980's. It does work and has a working power meter on it. The power meter actually does work and the circular mechanism in it actually goes around in circles when you plug it in. This is not a home made job either and I would assume was very limited in production due to the fact I've never seen another.......not on eBay or anywhere for that matter. There is a sticker on the bottom which says made by JA Company, and the power meter itself says DUNCAN ELEC MFG CO LAFAYETTE IND at the bottom of it. I would assume the shipping amount for it would fall in the 15 to 20 dollar range, I don't know really what to ask for it,......so how's about 49 bucks, shipped? A fellow collector e-mailed me and told me this certain power meter dates about 1953. It has been sold, but I wanted to add this info for anyone else who might run into one of these things down the road.
