OK....here is what we have.....................An ORIGINAL 1940's Lionel O scale transformer ..90 WATT. LOOKS to be intact. It worked in 1990. Was then stored UNTOUCHED in a heated / moisture controled basement. Switches move as they should. Might need new cord??? I plugged it in.....I didn't die....so that was a good thing!!!!! It SHOULD work, but I can NOT say for sure/ untested. You may get a working item or a really neat display piece for your train room!!! Be sure to check my GREAT feedback. Sold as is. I can not test it due to my layout being in a storage locker in pieces and my trains upstairs in storage containers.....sorry.
