     1/2" x 13 TPI is a standard ANSI thread, class 2A.

     Almost anything post-1949 will be either standard ANSI or standard metric.
Unlike my problems with the Model 15, which takes a non-standard mounting bolt
(3/8" x 28 TPI) which I had to make, the later stuff is standard.

     The NYC Resistors made a knob for a Model 15 using a stereolithography
machine.  Useful if you have a Model 15 with no crank.  See
