I'm very interested in whether these get IDed because I've got three Russian dyengas I got in a grab bag that are before 1600 (thus no Krause) but that I need to find a good reference for, and whoever can ID these probably has more info.

Strange text, turned in readable position.
Further remarks: "C"(=s) under horse and legend around rider.

The text is like "ѠСПОДАРЬ ВСЕА РУСИ" (lord of all russia). Could be denga of Ivan III Vasilyevich. What is the weight?
