You can now start the acceptance procedure (2nd check):
The band was checked by using slight punches with a small bronze hammer. If it sounded hollow the shell had to be returned to the factory for re-banding
The factories got the bands free of charge from the state arsenal where they got the order from. They got exactly the number of bands as written in the order of shells + 2% more to cover failures. If they needed more than the additional 2% they had to pay for the bands. The copper chips from machining + the left over additional bands remained state property and had to be returned.
