Adjustment and calibration tool

[pzgr40]

The buy of the day, the Just. Schl. 18 or Justier Schlussel 18, a calibration and adjustment tool for the fuze setter of the flak 18 anti aircraft gun. As only 1/ 10 of a second deviation plus or minus meant a difference of 80 meters above or below the enemy aircraft instead of beside, it was important to calibrate the fuze setter.
Cost me a small fortune, but an important addition to my flak 18 shells collection

Ps: BMV is the manufacturers code for Rheinmetal Sömmerda, Germany.
