Does anyone know where to find an instruction manual for a pressure canner from National Pressure Cooker Co? - national pressure cooker eau claire wis

The only other marks on the pot Eau Claire, WIS No. 7a and the lower half of the numbers 0048 600. I searched the internet and the only thing we discovered was gopresto instructions, but I do not know if you are correct. I would welcome any information and help!
