Dafuq is a "doshka?" Dashika maybe? 23mm what? The third pic looks like shit picked up at a WW2 battlefield. All good, "competent authorities" have it. Not showing pics and the article to any 0311 or 11B I know, they will laugh/snort beer outta dey nose and want replacement. If I can go there knowing the difference between a rifle round and a driver tip can I be a "competent authority" too?
