This goes with Paul Ernst's "Cramped Snipers Nest" thread and it concerns the ergonomics of the snipers nest:
Your Armpit To The Floor
Or Your Foot Out the Door
Or Your Foot Out the Door
Using the length of the Mannlicher-Carcano as reference, Figure 23 illustrates how cramped a gunman would actually have been; the rifle is at an angle of 45 degrees to the south wall of the TSBD, approximately the trajectory for a hit at Zapruder frame 313 when President Kennedy was struck in the head.
The sniper, could not have moved significantly to his left, i.e. to the south, because of vertical pipes near the edge of the brick wall...

In another article he writes:
The distance from the left edge of the window to the wall to the left of the window is approximately 22 inches*; perhaps it would be impossible, even for someone of Oswald's height and build, to crouch in that corner and accurately fire the 38-inch-long Carcano.
Without a substantial structure, such as stacked cartons of books, to provide mechanical support, perhaps it would be beyond dispute that it was impossible to accurately fire the Carcano. Source: The Sniper's Nest That Never Was / by Allan R.J. Eaglesham

We also know the sniper must change positions in order ot make these 3 shots.

...The target which was emplaced at 240 feet, as shown in Exhibit 583--we had rather an unusual coincidence with respect to this target. This involved the displacement of the weapon to a sufficient angle that the basic firing position of the man had to be changed. And because they knew time was very important, they made the movement very quickly.
...On the third target, the angle through which the weapon had to be moved to get to the third target from the second was relatively small, and there were only two rounds which did not hit the target at 270 feet. One of these rounds, by the way, was used in the sequence where the iron sight was employed.
These are the numbers Paul Ernst used and the sources he got them from. If you have other numbers then demonstrate those along with your sources
I think Paul got it right - if you don't - show your scale model of the what you call the proper measurements and position. Then the distance you get from the man's armpit to the ground in each of the positions as he points that gun out the window.
why is that? - that's the check - isnt it?
