Condition-grading criteria for HP calcs?
Some years ago (probably not here) I saw a discussion of grading criteria for calculators, HP in particular as I recall.

This discussion of related matters is helpful:

... but I wonder whether anyone can connect me with the piece I saw, or any such. It will help me describe the several HPs (16C, 32sII, ...) I am about to sell.

Many thanks to the members of this forum for their help.
