This old derringer....

I can't say much about the gun, but the book actually looks to be 'fake'. By that, I mean someone just took any old book and hand-drew a cover as a joke.

I think you are right about that. Check out this link for a more polished looking version which is clearly a modern BP gun:

It's a modern copy. We have two similar pistols in our next auction. Worth less than $100. Some are unmarked and some are marked "Jukar". Usually .45 caliber.

It looks like a reproduction Derringer to me made by Jukar in Spain. I picked one up at a gun show for $40 and refinished it. My Derringer looks exactly like yours. There are a lot of these out there in various conditions. Some were sold as kits and some were sold finished. Some of the kits were done very badly like mine. Yours looks very good with a correct brown finish on the barrel. Great find.
