Manufacture: Tuna Pressure Pans

Hi!

I purchased a TUNA pressure pan on e-bay a few years ago and itsn' in need of repair. The top is self contained, the pan has a rounded, "blown out bowl-style" bottom. The pan is SS and the top has a blue lever that goes across the lid of the pan and secures the pan with a simple turn. The pressure reglator and release valve is also on this apparatus. I can't find any information on it anywhere, especially where I can ask if it can be repaired....it is a wonderful pan and it would be a shame to trash it. Can you help???? Sure would appreciate your kindness in helping me locate the company so I can see what the problem is and if/how it can be repaired. Thanks so much!!
