These chairs are either from 1974 or 1982. Some have the date stamp on them of 1974 others have a date code of 1982 or the patent sticker states they are from the 80s. All the shell chairs I have listed have the swivel base on them and some sort of blemishes in the Naugahyde. I took photos of groups of 2. The description is all the same for all of the listings so please refer to the photos.
I was researching in the past about how to repair these chairs and came across a great article I wanted to share. There was a photo attached on a green naugahyde chair with yellow electrical tape on it. I can take base off shell and pack in one box.I will put the screws and washers in a baggy and mark each one with the chair it belongs to.
