Otto, yes this is the area I was referring to.
My opinion is this area should be inlet tightly and/or bedded on a 44 1/2. Doesn't matter how deep it is fitted into the frame just as long as its in. Also my opinion is the factory was in production and most guns were not for target shooting, they were just turning out product. Not that it make much difference now, due to wood drying out and time, but it might be interesting to see how a factory target gun was setup.
I've included your picture here in order to help show why I believe this needs to be done.
Looking at the front in the picture, the wood is bridged at the top, but is not at the bottom. The bottom is where the biggest concern is. By bedding the tangs and the front face of the stock to the back of the frame, yes, you get a solid point for straight recoil, but without the tenon set into the rear of the frame nothing is holding the wood from flexing or spreading at the bottom and away from the lower tang. The tang retains the wood on the inside, and the tenon, the spreading to the outside. The tenon should also do a better job of retain the stock at the top and not allow the top bridge to split down the center. Simply bedding the stock to the rear of the frame and tangs does not hold the stock from twisting out at the bottom. Just because there is a through bolt, that holds the wood against the frame, verses a couple of wood screws does not make up for the tenon.
Hope this clears up why I originally brought this up and my reasons why. Also apologize if I sound angry because I'm not!
