Test of the 53mm Fahrpanzer in
24 and 26 June 1891 the firm Grusonwerk of Magdeburg made severe test in the
proving ground of Sofia in order to show the performances of the of 53mm Fahrpanzer
recently designed by major Maximilian Schumann. A similar test had been made

Fire at a range of
The ranging fire was hampered and slowed down by the low density of air, due to the altitude of the proving ground and the high temperature (36°). It was carried out firing two shot at every elevation and was judged very effective, since it assured an exact observation of the fires without an appreciable delay in ranging, thanks to the easiness of handling the gun, which enabled to fire two shots within a brief interval.
The results of the fire were as follows :
1st row : 12 lines hit by 25 splinters and 3 shells or shell-heads;
2nd row : 39 lines hit by 312 splinters and 6 shells or shell-heads;
3rd row : 33 lines hit by 201 splinters and 8 shells or shell-heads;
Therefore 84 lines out of 120 were hit (70%) by 538 splinters or shells. The file of the central row were so thoroughly minced that was quite impossible to count the hits.
Fire at a range of
All together 119 lines out of 120 were hit by 187 bullets, 448 splinters, and 40 shells, shell-heads or fuzes.
Fire with case shot. The gun
fired at first 5 shots at ordinary fire, then two series of 20 shots each at
rapid fire, within an average space of 47 seconds. All the lines were hit by
1682 balls overall. Since the balls were

Fire against shooters. The
target was a line of laying down shooters placed at intervals of
The results were judged very satisfactory, since 46% of dummies of the first line, and 30% of the support line were hit, although only few ammunitions were assigned, and the target was not clearly visible, being hidden by bushes.
Fire against a field battery. The target was a two guns field battery with 7 gunners each placed in open ground, with the limber unhooked behind, both at an unknown distance. Guns, limbers and gunners were represented by dummies. To appreciate the effect of light calibres against field artillery, the gun, after the adjustment, should fire 23 ring shells.
The results were as follows :
- right piece : gun – 1 splinter and 12 holes, 2 gunners - 2 splinters and 12 holes, limber – 2 splinters;
- left piece : gun – 1 splinter, 3 gunners - 2 splinters and 8 holes, limber – 4 splinters and 27 holes.
Observation of fire. In
