Some more stuff from my almost-forgotten cigar boxes. Just hope this is considered ammunition-related by the administrators.
This is a box of copper cylinders for a copper crusher device. These were used to test the pressures of ammunition. In a previous post, I sent the link to a pdf document where the procedure was briefly explained.
Here’s also a calibrating table that came inside the box. It is dated 1945. If one measures the cylinder’s lenght after firing, and checks the table, the pressure is given.
The pasted label translation reads:
PRECISION WORKSHOP AND ELECTRO-TECHNICAL CENTER
100 copper cylinders 7 x 5 mm for manometers small model (5 mm piston)
TABLE NUMBER 2.004
Wrapped and pasted around the other three sides of the wooden box there’s a copy of the pressures table, number 2004.
There are 4 or five copies of the table inside the box, wrapping the paper tubes containing the copper cylinders. This should be for cushioning and avoiding them to dent.
