Take a look at

Two books with scans are available from Howdy Herz whose email address is on a post today and Richard Anderson whose address I think is rbaonstrikes@lvcm.com
Another good book but without scans is by Jom Turnbow.
Janice O'Neal (junkman3@aol.com) puts out a great list of all Nevada strikes at a great price.
