These are probably some of the rarest, although they are all pretty hard to come by, pieces I've seen. The first two are Canadian National Telegraphs & Cable and a Canadian Pacific Railroad Telegraph cable Co. The next two are for Mackay Radio with the second marked American Cable & Radio System. Last is an RCA (Radio Corporation of America) round box. Cool lightning bolt on the handle. Classic pieces. I wish I had them all. If anyone has any different types than what I pictured, I would love to have a picture of them to add to my reference folders. There's got to be more out there. I know there are tons of different Gamewell Police and Fire boxes so the telegraph boxes should be no different. The Fire and Police boxes are a different subject alltogether but are extremely awsome as well.
