Jim,
I found the Tamgas on the net:
www.gaumina.lt/totoriai/english/tradicijos_info3.html
The page cites a 1930's Polish publication by Stanislaw Dziadulewicz entiteled "The Collection of Emblems of Polish Tatar Families";
I assume the plates are form this particular work.
I beleive that with this purchase I have opened up a whole new fixation for myself, now I feel I will be hunting down pieces of Tatar armor and equippment...
