Pricey, though. The less expensive of the two available is $82. There's one on Ebay for $120.
I think it sold for about $30 new. Most of the info you would need could be obtained from websites dedicated to the particular camera or shutter you want to work on.
I bought a copy from Ed Romney about 15 years ago. I don't think there is much in there that can't be found anywhere else.
