J-38 Knob 16.5 mm Radius

Has your J-38 Key broken off it's knob? Well mine did after almost 30 years of existence. This is a knob that will fit right on there. It's 33mm diameter is comfortable for my hand. Could easily be scaled up or down to suit your need. The hole for the screw is pretty small as the screw holding my old one was, but it could easily be made larger to accommodate any screw size. 73'
