It was impossible to find a Joy Manufacturing Co. visigauge, so I decided to reproduce one. A generous pump collector had a sand cast top dome that I purchased, the aluminum base plate was made at a machine shop, and the other parts I purchased from a hobby store, plumbing supply houses on ebay, metal supermarket and repurposed them. I have never seen a visigauge as wide as this one, but I am sure there are others. The diameter of the top plate and base plate about 6-1/4". Also never seen a brass center spinner like this one.
