While looking for ways to make a Thompson Center Contender more of an off-hand gun, without installing a (costly) adjustable buttplate, or fixed Schuetzen style BP (would be more period looking!), I came across the adjustable hook modification on the Springfield Model 1922 International Match Rifle, 30 cal. Illustration from Brophy's "Springfield 1903 Rifle", page 110. NOTE: There was a 1924 International Match Rifle as well, I believe it also could have the adjustable hook. Also, you may see pictures with a Schuetzen style buttplate, with one tail on the lower side....

From the side, you see the tightening screw.

Next, four unique and important refinements were added – a red fiber butt plate, an adjustable palm rest of new and improved design, and an adjustable front sling swivel. The fiber butt plate provided a comfortable and non-slip finish to the stock which may be fashioned with a rasp to give any degree of curve large or small to insure a comfortable fit of the shooter’s shoulder.
Into the rear face of the red fiber butt plate a channel was cut forming a sleeve for the lower prong – a steel arm which will steady the muzzle-heavy rifles in off-hand shooting. Its adjustable and detachable features permit of its being placed in the right position for any shooter, reversed so as to be out of the way, or removed entirely. NOTE: With all due respect to William Brophy in The 1903 Springfield Rifle, page 110, the date of this article is NOT April 1, 1922...
See the important parts. It appears that the angle bracket is attached at the top of the stock with a screw entering the stock vertically. The angle bracket appears to have a fin that may be the width of the hook, and if so, probably fits inside on top of the prong inside the milled channel within the stock. The upper screw secures the top of the inner spacer against the prong, and the tightening screw levers the bottom of the angle bracket down and against the bottom of the prong. There is a "T' nut down at the toe of the stock, the prong most likely has a milled slot just wider than that tightening screw, the tightening screw squeezes the inner angle, and clamps the upper arm of the prong. So the hook can be slid up and down on that T nut, and the tightening screw clamps the inner spacer against the hook. Spacer MAY be a metal bracket, with a wood, cork, ??? pad on the hook side...
Is there a better view of this adjustable hook someplace?
