How about a used K&R map measure?

As shown in the attached image, I am listing a map measurer made by K&R in Germany.

It works by rolling the toothed wheel at the tip of the unit over a map and displaying the distance according to the map's scale.

I no longer need it, so I would like to pass it on to someone who can make good use of it.

Weight: approx. 27g / Model number is unknown.

Main unit dimensions = Height: approx. 54mm (max) x Length: approx. 110mm (max) x
Thickness: approx. 17.5mm (with loupe folded)

There are no practical issues, but this is a used item and the dial has faded, and there are signs of use (the loupe has yellowing and scratches). Therefore, please refrain from purchasing if you expect a new, unopened appearance like those found in stores, or if you are in a hurry.

I will answer questions as much as possible, except for those regarding purchase date and usage methods. Please understand that returns are not accepted, so please purchase after acknowledging this.
