Can speedometer glass be polished?

I'm looking for a speedometer for my project and most of the gauges I'm considering have pits or scratches in the glass.
1) Can scratches or pits like these be polished out, or should I keep looking?
Thanks

If you polish out the scratches, you will probably end up with some optical distortions in the glass.

If you can't find an NOS glass, sometimes a good antique watch/clock repair shop can come up with convex glass in that size range.

Good luck.....

I routinely polish both watch crystals and glass with a product I get at my Ace Hardware Store. It is called "Wenol" and it has no abrasives. I even clean the plastic on my head lamp covers and always comes out nice. My wife uses it on the mirrors in the house too.

You might try one of those headlight restoration kits?
Basically ... very fine sandpaper, polishing compound and an applicator / buffer.
