The Sniper's nest ergonomics.
« on: June 19, 2019, 08:17:14 PM »
I have been trying to find the dimensions of the boxes in the sniper's nest in order to create a mock up for evaluation of the ergonomics in the nest. The following is from WC testimony of Studebaker. Does anyone know the dimensions of the boxes or where I can find them? Also I would like to know the height of the window sill above the floor. Thanks.

Mr. BALL. Do you have the measurements of the boxes?
Mr. STUDEBAKER. Yes, I have all the measurements.
Mr. BALL. Where?
Mr. STUDEBAKER. Down at the city hall.

The box dimensions were mentioned in the Warren Report. They called them "cartons" and gave the approximate sizes.

There are pictures of the boxes at the National Archives with a scale beside each. ( You are not allowed to view links. Register or Login ) However you have to calculate the effect of perspective since the scale (in most cases) is not on the same plane as the boxes.

The measuring stick appears to have each unit being 1/10 of a foot instead of inches. Do you know if this is true or not?

It's a surveyor's measuring stick and each foot is metricized.

Correction!!

"Box A" is the box on top of "Box C". "Box B" is the carton on the window. The surface of Box A has the gouge on it; the same box with the gouge is seen on top of Box C in this Crime Lab photo.

Wondering what the object on the floor is. Seems like a light bulb or a stubby screwdriver.
