Guy,
in your dad's library is the book : "Damascus steel" by Manfred Sachse with several type of Damas ( european and asian)
In the book : Bei Schah Emir und Khan" by Balsinger and Klay are also at least 5 types of Asian damas. I attache a scan of the latter picture.
If you come at home you'll have a better look !!
Your dad
Michel
