УЧ Б marked Russian training guns

[Larry D.]

Since we're necro-posting......

Is the designation used to denote a non-functioning weapon to be used for training?
Or for a functional weapon marked so that it stays with the training units?

Usually functional. Usually assembled with rejected parts

Since this is connected to the 1950 topic I figured I'll necropost it here.

The mark looks to me to be "УЧ Б" not "УЧ Ы". The two vertical lines that make Ч look like H and Б look like Ы seem to me like they are related to each other and unrelated to the УЧ Б stamp. This does not change any of the discussion, it is of course a training (УЧебный) SKS, but Б makes more sense. There aren't many Russian words that start with Ы.

agree, it's letter Б, not Ы

I can see that.  Hadn't noticed the upper horizontal flag on all the examples. 

What do you guys think the vertical lines mean then?  Why obliterate the Ч and make it look more "H" ish and the Б and make it look more "Ы" ish.  It's done on several examples I show above.
