Internal numbering goes back to Imperial times. Navy side-plates had the first two digits of the serial number stamped internally. The first or second digit was stamped ahead of the receiver lug, but not for all models.
The short answer is that we don't know why they did it, but it probably seemed like a good idea at the time. Norm |
