So all the talk about Dial Calipers got me thinking I should dig out my Brown and Sharpe and give it a quick Rub with a Oiled Cloth. When I pulled out the Cigar Box it lives in, I found this Old Soldier which I had Forgotten about.
As you can see, they are pretty much a mess. The Zero is about .010" off. And it is a Miracle that the Dial Pointer didn't snag on the inside of the Broken Crystal.
After a Search of e-Bay, I found a 37mm Crystal from a seller with Good Feedback that should fit.

So now the question was should I attempt to Fix the Zero. I've seen people do it. And
Most of the time it works. What they heck. Lady Luck Favors the Bold ...
Gotta say it was a Little Dicey. And I'm Glad I was wearing Reading Glasses when I did it because the Pointer Popped Off like a Champagne Cork right in my face. But I got it done. And Reset the Zero.
And then Bingo Bango, here it is with the New Crystal installed.
Really surprised how well things turn out. Given it is a 30 Year Old No-Name Caliper.
