Paralelloscope Bracket

[Alex Blair (RIP)]

In the cab of my FGT There are 4 holes in the roof in the shape of a square, in the manual it says they are for mounting a paralelloscope bracket. 3 questions

1. What is a paralelloscope ??

2 .Does anybody have any pictures of what the bracket looks like ?

3. Can anyone give me the dimensions of this bracket (so I can make one) or does anyone have one for sale ?

As always any help is gratefully received

Richard It is probably an instument for measuring and mapping..Only an educated guess ,but is probably related to this formulae and relationship......

Abstract
Assume that a parallelotope P is inscribed in a three-dimensional convex body C. A conjecture says that w-11+w-12+w-13>=1, where wi is the ratio of the width of C to the width of P for the direction perpendicular to the i-th pair of parallel facets of P. We prove three weaker inequalities. One of them is w-11+w-12+a-13>=1, where a3 denotes the related axial diameter of C.
