Are their any reasonably economical options on Mitutoyo dro glass scale replacement? The display is a model PM-32L, and works fine, but is obviously pretty old. The broken scale is code 529-108-105, model AT2-750. If glass scale replacement is impractical, what’s the best new option for less than $750? Magnetic or ? The unit is on a Wells Index 650 mill that’s new to me.
