I think you are thinking of the Kleenrite tools. The Prochem has a great design its just heavy.Is that the one that looks like a hair dryer? If so, I've got a pair of them that have got to be 20-25 years old..... The thing looks like a dinosaur..... I keep meaning to try them, just have never gotten around to it......
I'll take a pic. and post it..... I have no idea who they are made by..... You are probably right.......when I'm @ the shop tomorrow, I will snap a pic of some of the old gear I've got.......I think you are thinking of the Kleenrite tools. The Prochem has a great design its just heavy.
