  1. “.224 Valkyrie”
    This cartridge dimension-wise looks close to 5,45×39. Was it intentionally made to make it easily confusable with said cartridge?

  2. Question asked at @20:50 regarding design an setup of sights in past. I believe one tool used were witness cards mounted at certain distances from muzzle and height in anticipation of vertical coordinate. This is not to say theoretical calculations were useless, but they alone would not be enough considering importance of the work. In my past experience I have seen use of witness cards to evaluate state of bore wear (by bullet yaw).

  3. [off-topic so ignore if you wish]
    Article about so-called AKMSU was published in Russian here: https://kalashnikov.media/news/4522523
    long story short: one smith from Pakistan get PRC made clone of Kalashnikov, added wooden furniture with grip which is supposed to look like Soviet made and added special muzzle device. Then sold it and after some changing of owners it finally ended where it is now – in collection in Great Britain. Thus so-called AKMSU was NOT developed or crafted in Soviet Union.

  4. “Alternative history: PMC armament in the 20s and 30s”
    Well, in fact usage of almost any production fire-arm, which do not break time-line (like weapon which production started in 1927 appearing in 1921 or so) could be explained, more or less logically.
    Things to consider are which country is backing (or at least ready to sell some weapons) and profile of mission. On other note if you want to have automatic pistol and sub-machine guns or rifle and machine gun it would be logical to have them use same cartridge (same chambering).

    • Also, for 1920s European setting, you can just use browning to denote automatic pistol, not necessarily designed by J.M.Browning (proprietary eponym).

  5. The Naval Air Museum in Pensacola, Florida has a Davis Gun if you are looking for one. Pretty neat. Jordan is a beautiful country. I hope you make it out there.
