Detailed information is now available concerning the Skoda 75/49 AA/AT gun
which has appeared recently in the Italian army. This gun may be designated "75/50" by
the Italians. Characteristics of the weapon are:
|Muzzle velocity || ||2,690 fs|
|Maximum horizontal range ||16,150 yds|
|Maximum vertical range ||10,000 yds|
|Practical rate of fire ||20 rpm|
|Weight in action ||2.76 tons|
|Weight in draught ||4.13 tons|
|Elevation ||0° to +85°|
|Weight of complete round ||25.7 1b|
|Weight of shell ||13.9 lb|
For transport, the equipment is carried on 2 two-wheeled bogies at the front and
rear respectively. There is a superstructure with a seat on the rear bogie to
permit a crew member to operate the bogie brake.
The bogies are detachable and two hinged platform legs can be swung outward at
right angles to the central member to form the platform. There is a levelling
jack at the end of each leg and at each end of the main girder.
The piece is fitted with a muzzle brake. The breech block is of the vertical
sliding type, opening downward. It closes automatically after a round has been
fed into the chamber. The buffer and recuperator are slung under the piece. Documents
give the elevation as 85° although examination of the numbering on the elevation
arc suggests that this is graduated in sub-divisions of 20 mils and divisions of 80 mils
up to 1,280 mils (71° 53'). The piece is elevated on two toothed arcs between
the trunnions, compensation being by two cylinders housing springs attached to the
cradle by wire cables.
Receiver dials are fitted. A leaf and blade open sight is integral with the
piece. A Czech ZRz dial sight is fitted, the horizontal graticuling being in 5 mil
divisions up to 20 mils on either side of the single vertical graticule. Magnification
is low, and in a captured piece optical quality was bad. There is an electric
graticule illuminator for night firing. This sight is protected by a grid when a
tarpaulin or camouflage net is covering the equipment.
Three men are required to lay the gun. The gunner for direction and the No. 1 roughly
for elevation. These men sit on the right and left, respectively, of the piece, facing
the line of fire. The No. 2 man, who faces the gunner, completes the accurate elevation
of the piece, sighting through an eyepiece on the other side of the telescope.
