David, 
 I do not think so. 
 Yours is a classical "Bukharan" saber of a shashka-like form with 5 rivets  ( we discussed them already). 
 The one from Czerny's is a totally different animal, IMHO. Much closed to the Afghani "pseudo-shashka". 
 
P.S. 
 
 
 A friend of mine from Belarus sent me pics of that sword published on another auction. Here we can see the upper part of the blade with the "box-like" system of fullers. 
 AFAIK, this is very typical of Afghani blades.
