Well, just entering into the spirit of the 
thing. Personally, I consider the whole issue of 
pre-1917 discriminations somewhat superfluous. 
Just like your English case, really.

Excepting the Petrin reforms and IO 
introduction, before 1917 there were no 
clear-cut boundaries, and the changes just mean 
some letters gradually falling into disuse. I 
guess I might dig out a history book which would 
attribute those interim changes to some texts, 
but would those markers be truely recognisable?
