Does anyone know if someone out there has made the scalloped glass domes that go on either side of an American # 500, # 510, or # 550 top? Thanks for any help or information. Goober

I know there is someone offering plastic reproductions but every one I've seen has a noticeable sag in the middle. I am currently working with an individual to reproduce the corners in milk glass but it is going to take some time before we know if we will be successful.
