Ol _Deuce, 
That is AWESOME rifle!! it looks to be in A plus shape!! when it comes to finding the book, you can find them, but they are pricey. I bought 3 last months, but they are all gone.  i sold them for $65.00 shipped media mail or $70.00 priority mail. If you have no luck, I might be able to come up with one. I talked to the dehass family, and they are not going to do another reprint. If you don't find one, let me know, and I will start looking!
