Mojjax, glad to hear it is about fly fishing..
Fly fishermen are a pretty zealous lot, and among them are many
collectors of vintage works involving fly fishing.
At this point, were I to list it on eBay, I would title it something
along the lines of: "Fly Fishing Kashmir - Scarce Volume"
Be sure to note ALL of the books condition issues in the listing, as
well as including images of the title page, front and back covers. So
long as the condition issues are noted, you won't hear from an angry
buyer who expected a perfect condition book. It may not have much
of an effect on price, considering it's scarcity.
That, and I would start it at $100.00. The bidders will do their own research,
and find that it is, indeed, a scarce volume. All you need is 2-3 seriously
interested parties, and you've got a great auction.
