The Royal Library in Denmark have a manuscript that they call 'Illustrated work with horses from Nepal' among their Oriental digitized visual art site. The book is presented in a good quality flash site (about 50 pages) and you get a bigger viewing field if you enlarge the browser (unlike many other flash zoomers).
All of the images above were spliced together from screencaps. I've touched up that final image to remove some pencil markings, but left all the others as found.
There appears to be no background information available on this work, even in the Danish section of the site. I have no idea when this manuscript was produced -- even a rough guess would need to cover a few hundred years, say 17th, 18th or 19th centuries perhaps??
The devanagari script makes no sense to my hindi-speaking mate, so presumably it is written in Nepali.
If anyone knows anything more or can find any information about this work, please let us know by either commenting or dropping me a line (peacay AT gmail DOT com).
UPDATE: Christies listed an item a couple of years ago that is either a copy or a derivative work:
"A Treatise on the Nature and Illnesses of Horses, Asvasastra(I think leporello means folded paper like an accordian) THANKS Tonya!
Nepal, 18th Century
Leporello manuscript on composite native paper, stained yellow on one side, 6 to 9 line of Newari script in black ink, with 32 miniatures of horses, 19 half-page illustrations on the yellow side and 13 on the white side, 22ff."
