Smith Tachometer

[gt8610a@prism.gatech.edu (Thomas Augustus Kimberly)]

My tachometer in the TR6 has ceased functioning properly.  The needle
reads about fifteen percent too high which is fine at low speeds but it
sits in the red the entire time at highway speeds.  Is there any source
for a Smith tachometer out there for less than ~160 dollars?  This is the
'72 style;  I know that it changed in '73.  It would be really nice to find
a electronic replacement that used the same face.
