Sure. Emma Astvatsaturyan in "Turkish Arms" explores the collections of two leading Russian museums: the Hermitage and the State Historical Museum. This is a large and sufficient sampling. The largest number of dated yataghans in this sampling falls on the period from 1786 to 1825. Then their number drops sharply (there are dated yataghans after 1825-26, but there are much fewer of them). And around about 1850, their number increases again. At the same time, they have serious differences from the yataghans before 1826. In addition, the author groups yataghans by types of blade decoration. This type, as shown here, has the last date of 1825 and does not occur at all later (Astvatsaturyan name this type yataghans East Anatolian, Elgood assumes its Greek origin. The engraving on the blades really resembles the Greek one, similar is present on Cretan knives). The author assumes that the production of this type completely stopped at this point. She connects this fact with Mahmoud's reforms in the Turkish army and the transition of its weapons to European models. I think this is more related to the liquidation of the Janissary corps. Probably this process was not uniform throughout the empire and on its periphery the production of yataghans did not slow down so much (most likely in Albania and Croatia, where bektashi (banned by Mahmud immediately after the destruction of the Janissaries) and fugitive Janissaries found refuge). But in the central regions, production slowed down so much that some traditions were lost.
