PTC Instruments shore type D scale durometer model 307l with case - $135 (woodland hills)

Here is a PTC 307L durometer.
It is a type D durometer by Pacific Transducer Corp.
It has some engraving on the unit from the previous owner.
IT has a small little bracket that says 040 on it , it looks like.
From what I understand this is a shore type.
I pressed the pin on the bottom and it moves the needle up and down.
It has a set needle I can move back and forth.
Check out the pictures.
If this unit requires calibration, you are responsible for the calibrating, since I do not know when it was last calibrated.
