Ive aquired a vintage Knapp Monarch autoclave/ sterilizer with the KM stamp on the peice, patent applied for also stamped into it. It has a cat # 150 stamped into it. It's cylindrical with fold out legs and about 16 inches long. it has a slide out tray and 2 steam ports one on each end. Does anyone have any kind of information about items like this that Knapp Monarch may have manufactured, because I cant find anything about it researching all Knapp Monarch sites
