There are a few things to consider here. Today we have a notion that everything that fits together, should fully, fit together. That is, screws should fit flush with their counterbores. When looking at the original drawings, the depth of counterbore is not dimensioned, at all, however the relationship is driven through the "thickness" or the face that the screw bottoms out on. Which is what really matters.
The front counterbore is thus driven to be 2.8mm deep, and the rear 3.5mm, while the screws have a head thickness of 5.
I frequently challenge collectors, and people in general, just because you *think* something does not appear correct, does not mean that 150 years ago it wasn't. I have seen many a gun, and a plethora of other things badly mutilated or altered because it did not fit the persons preconceived notion of "correct".
