Some gauges at auction--what are they for?
 

I would say that they are all to do with front sights, their heights, profiles and widths

21.5 buyers premium on top of hammer amount.

Reminds me of what I try to avoid walking the barnyard.

G2

front sight gauge
 

Here is one up closer, used to measure height of the front sight with relation to the bore's axis without regard for different barrel profiles. This one is set up for the 7.65 barrel and can be changed for a 9mm one.
Can anyone tell me what the 10/G represents.?

Rear Sight
 

The short one gets inserted in the P.08 toggle hole of the rear axle pin and would be a measure of the rear sight, too high or too low.
