I have a Mitutoyo DRO on my lathe where the plastic sheet that covers and labels the buttons has cracked and is falling apart. It is a PL-325L, and there's a picture of it here
I'm guessing this DRO box is at least 20 years old, so I'm kind of doubting Mitutoyo would still have parts for it.
I suppose I might be able to make some kind of plastic sheet to replace the original, but it would probably look crummy (although maybe not as crummy as it looks NOW!)
All suggestions welcome.
