Butt plate

This question may have been asked before. What is the significance of the four stamped numbers on some JSAR butt plates.

Nobody really knows why some buttplates (and bayonets) have 4 numbers stamped on them. We do believe that this was done after manufacture and delivery.

It is my guess that they were added in foreign arsenals. Most other countries are parenoid about their military weapons getting out in possible rebel hands and they record all sorts of numbers such as the numbers on some bayonets.

I believe Joe's right. Those stamps are a sure sign that the gun (or at least the butt plate) spent some time in South America.
