Hi all I need help please in identifying this shade. Im wondering is it could possibly be from an Aladdin or some other gas lamp. I don’t think it’s from an electric one. It has a scallop top and internal markings like a zebra built into the glass making it quite unique to anything else I’ve seen around. It has a rough cut rim not sure if this is significant in helping age it. Its also quite heavy and not light and thin, its built like a tank lol. Below are some photos in helping me identify this shade. Ive also attached information on a shade similar to mine. Regards Darren
