So found these calipers and do not know what this little notch is used for. Any Ideas?
Also is there a particular name for this style of caliper or is this a generic vernier caliper?
Well the scale has some numbers reversed on it.
So maxes at 6 when fully closed.
When that scale is at 0 (Fully open) does that notch line up with the end of the caliper?
Just wondering if it was meant to catch and stretch something maybe?
