There's actually a lot available.
The NRA has firearms disassembly manuals which cover classes of firearms.
Sample:
http://www.nrastore.com/nrastore/ProductDetail.aspx?p=BK+01616&ct=eThere's a "Book Index" right there in that link, too.
I've also searched online in the local library for manuals on disassembly and when my son and I were taking my Model 19 apart to put a new barrel on it, I found one for revolvers which included that model -see avatar.
There's also George Nonte's books on gunsmithing and firearms repair. Example:
http://www.amazon.com/exec/obidos/ASIN/0811712656/?tag=2ahawaii-20Also, many models are very similar or identical internally, and for instance, the one for the Model 19 also covered a bunch of other models that had the same lockwork, like the S&W Model 10. The manual I got also included tips and hints for avoiding "gotchas" for various models, like the variations on barrel pinning and the like.
The library also had one on semiauto handguns, as opposed to just wheelguns.
However, some things I've wanted in the past had to be searched for in the entire CONUS library system and sent to my local library on the "interlibrary loan" database system. One book I was looking for had to come out of the University of Idaho, not even a "public" library. I don't know how that would work for the Islands, with the shipping problems, though.
And at least in my experience, a lot of librarian-types (forgive me for "profiling") are pretty anti-gun, even here in Colorado.
I remember seeing a sign on the library information desk at one library which touted the First Amendment (free press) as saving us all from tyranny, and when I offhandedly and without malice aforethought (honestly!) asked about the Second Amendment, she screwed up her face in a Ewww! expression and informed me that it was obsolete and should be repealed.
An obvious case of gunsisbad brainwashing.
Or maybe "braindirtying" would be a better expression.
