A suggestion, I sold one to a member her not too long ago. What helped sell it was a video I posted on you tube shownig how well the meter worked. It reported smooth and in good shape. From what you have shown it could have stripped gears, busted needle or anything that a buyer might see as an issue.
Get a video and a set of pics showing the complete meter detail not just the image of it nested in the box.
