Look up Mirro's web site and you'll probably find the parts you need. Barring that you may have to carve one from hardwood. Mine is a 35-year old Sears Harmony Maid, aka Presto. I have found parts at the Mirro site and Sears still carries them too. If it's the round handle that has a long screw jobbie going down the middle you can get a one-inch hardwood dowel and drill the proper sized hole in it. I hope your National is also rated as a pressure canner. Pressure cookers don't usually have to handle the pressure a canner does.
