Looking at the first pictures again, I think I have it. (but maybe not!)

You will note in Sir RPG's book, that the grooved area where the bolt lies, Crossbows can be made in various shapes, some convex and some concave along their length. I see in the first pictures posted, that there is a slight groove at the rear, and a deeper groove towards the front of the stock where the bolt lies. This arrangement is to be seen on page 70.

Cerjak,

A question if I may;
If you lay a straight -edge in the "bolt groove", does it touch at both ends and miss the metal bridge part of the bow?
In other words, is the grooved area slightly concave or dished from end to end??

Edited to add, after Another look;

Is the bow seated as deep as it will go into the stock??
I ask, as the 'wing nut" on the underside is only half threaded onto the bolt, and it looks to me like the bow could be tightened down into the stock more, causing the bridge area to become flush with the surface where the bolt lies.

Corrado,
Thank you for getting me to look at this closer, it is a very interesting piece!

Dear Richard
Yes the bow could be more into the stock
May this pictures will help you.

Best
Cerjak
