German OOB 16: minor corrections

[Pibwl]

On the other hand, in spite of small caliber, it used HE shells (relatively long - http://odkrywca.pl/forum_pics/picsforum6/p064.jpg), so maybe it should be more than HEK 1.

According to Russian Natzvaladze (although probably basing upon some other source), ROF was 12-15 RPM, so it was quite big for a single-shot weapon. Also he gives penetration "at the attack angle of 60deg.": 60mm at 100 m, 19mm at 1000 m.
