Some books about the care of firearms.
From my library:
"Gunstock Finishing and Care" by A. Donald Newell.
This book has detailed introductions to various woods for selection on gunstocks. It also has instructions for methods of application amd treatments for early gunstocks, inculding militry, antique and early gunstocks.
"Bob Brownell's Gunsmith Kinks." Edited and Compiled by Frank Brownell.
This book is a hoot! But it is also filled with hundreds of hints and techniques that can be used by anyone! It comes from the correspondence between Bob Brownell and thousands of gunsmiths over many years.There is a complete section on the Gunstock.
"Gun Owners Book of care, Repair and Improvement" by Roy Dunlap.
This book has a complete chapter on the gunstock, with full details on inletting for the receiver and triggerguard assemblies.
"Professional Care and Finishing of Gun Metal" by John E. Traister.
This deals soley with the metal part of firearms. Lots of useful info in this book, inculding plating, browning and blueing gunparts.
I hope you find this helpfull. Sorry, no ISBN numbers, all the books are too old for that!:D
