A captured document from the Middle East gives some information on these cartridges, which
are fired from a standard Very pistol, either held in the hand or placed on a stand. The
size and weight of the cartridges are as follows:
length - 135 mm (5.3 in)
weight - 96 gm (3.3 oz)
The cartridge may be easily recognized by the closing disk, painted white, with the
inscription Fallschirmpatrone für Windmessung on the side.
At the highest point of flight, about 70 meters, a red parachute to which is attached a
silk ribbon 1 meter long and 4 centimeters wide is released. This
ribbon is held taut by a small iron weight.
Comment: This parachute would give wind data accurate enough for use
by field artillery. Although no details are available as to the scale of issue of
this equipment, it would be of value to units other than artillery.
