And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
This is a prime example of old school machining at its best. Machinist square, feeler gauges, thread pitch gauges, a 0-1" OD micrometer, an old school depth gauge, plenty of rules, triangles, squares, and (4) veneer calipers, each capabile of .001" resulution. The round things at the top may be PI tapes. In the days before large OD micrometers, PI tapes could allow someong to measure a large diameter round object like a paper mill press roll to .001" The triangular thing at bottom left is probably a taper gauge. The tall thing at bottom center is a height gauge.
It is amazing how much precision was availble to a machinist 100 years ago! The two items at the bottom are probably precision straight edges.

Oops. The triangular thing at bottom right is probably a taper gauge.
