The more I dug into the old stock, the more it is not worth repairing.
At some point, a P.O. cut the wood behind and thusly eliminating the rear barrel band.

I'm not a gunsmith, but I do understand quite a bit about stress points.
Without that band, when the cartridge goes bang the entire action free-floats placing all of the stress on the wrist and the trigger screws.
Lucky that no one got impaled.
