Seller: banjo-joyce (639) 98%, Location: Rayland, Ohio, Ships to: US, Item: 283573739679 Vintage Porcelain Heat Grate Floor Door Gas Register Gas Heater. Not sure what this was originally on but a neat piece which would look great in the right place. Consists of the main frame, a removeable door and a grate piece on bottom that comes off. I think it was on the front of a gas heater on a turn of the century home. If you want to educate me feel free to tell me who made this and what it is. Some of the porcelain has wear as seen in the photos. A second one is available for double the money plus reduced shipping and the second one looks unused with very little if any wear on the porcelain. Measurements 14.5x18.5" width/height and the door is 8x9.5".
