Story Dha- Burmese?

[D. Cooke]

This was my grandfathers, now my father's. He puchased this at Auction in Germany or Austria approx. 40 years ago. I recently came to learn that this was called a Dha or Story Dha and after a google search found some links to ths forum. I thought I would post these pictures here and see if anyone had an Idea about what the story is, how old is it? Etc.

Thanks in advance
