Does anyone know what's the font used in the following pictures? Indeed this math font is very common in many Russian math/physics textbooks published last century, and it appears in almost all the Russian math textbooks that I've read.

  • Sure it's not handwritten? There was some kind of standard technical lettering before the CAD times. – Oleg Lobachev Apr 06 '19 at 13:28
  • Hi Oleg, thank you very much for pointing this out. I found that some books with the above fonts were published around 1970, even older than the initial release of TeX. – Ce Shen Apr 06 '19 at 13:54
  • Welcome to tex.sx. I'm inclined to agree with @OlegLobachev, that these diagrams were prepared by hand. Look carefully at the two "2"s in the second image; they are very similar, but not identical, and I don't think that's the result of a low-resolution scan. This reminds me of results obtained from using a Leroy set. (That was a commonly used drafting tool in the era before computer typesetting became available. The description linked by Oleg is the comparable tool for Cyrillic.) – barbara beeton Apr 06 '19 at 20:27
  • OMG I forgot we had rOtring NC-scribers only as recent as 1980's (the dawn of switching from stencils to electronic lettering) pre personal word processors –  Apr 07 '19 at 00:31
  • @barbara beeton, thank you very much! There's a slight difference between the two "2"s, and now I believe that these letters and numbers are prepared by hand. According to another post and a paper, it seems that the old Russian or Soviet typographical style hasn't beem implemented hitherto. If so do you have any idea from where the original templates or stencils can be obtained? – Ce Shen Apr 07 '19 at 10:18
  • @CeShen -- After some digging around on the web, I haven't found a source of Cyrillic templates, but I found this site with a lot more information on the use of the Leroy set: http://www.benzilla.com/?p=5433 . Since the author appears to be very knowledgeable on the subject, I've posted an inquiry asking whether Cyrillic templates existed. I'll report if I learn anything useful. – barbara beeton Apr 07 '19 at 15:58
  • Look what I found! – Oleg Lobachev Apr 07 '19 at 21:39
  • @barbarabeeton Thanks, indeed I'm willing to make this font via fontforge if the original templates can be found. – Ce Shen Apr 08 '19 at 14:29
  • @OlegLobachev That osifont is interesting but is still different from this one. I'll ask the author whether he/she knows more similar font candidates. – Ce Shen Apr 08 '19 at 14:34
  • @CeShen -- There are actually computer fonts available that are based on the Leroy styles. And used Leroy sets are also available. A Google search should turn up quite a few options -- but be selective! (Good luck!) – barbara beeton Apr 08 '19 at 15:58
  • Is this issue solved? How? – Mensch Aug 25 '19 at 08:58
