German Artillery

12cm Kanone Handheld Range Drum

Above:  This is a very unusual Range Drum. Most are permanently attached to the gun.  This one is removable and is placed on the face of the breech-ring rather like a gunner's quadrant. While comparing this range drum with another very similar one for the 15cm RK, I now believe that the mechanism for this drum is reversed

Above:  As the drum is moved to indicated gun to target range, the rectangular brass vile bubble mount moves up and down.  With the range drum placed on the breech-ring the barrel is elevated until this vile bubble is level.  At this elevation the projectile will achieve the range on the indicator when the piece is fired


Below:  This is a 12cm Kanone with its crew.  Notice that the NCO on the far left is holding a range drum of this type
