The tachometer on my 1942 10EE had the glass and hand missing, plus the dial was destroyed, as you can see here:
I spent most of the weekend rebuilding it:
Cal sent me a photo of an original dial, which I digitally cleaned up and then printed to size on paper, which was then glued to the dial plate. The original arbor had a pivot broken completely off, but fortunately, I also dabble in antique clocks and so could remake one. The new "glass" is acrylic. I spent some time buffing out the worst scratches in the bezels. Everything else was cleaned and lubricated. The original hand was white, but I found this red hand from a quartz clock in my box of scrap clock parts and adapted it. I like it better! Very visible.
Just for reference, here are the inside parts of the tach:
