This looks similar to one my wife and I just bought. Trying to find info hasn't been helpful, but I have learned that JJ Cress Company was a kiln manufacturer that appears to have turned into the current Cress company in the early 70s. JJ Cress Company opened in the late 50s. Can't find much more info on that other than if you found the serial number the first two digits of that are the manufacturing year, so mine would have been made in '69
