I just got a set of replacement labels for my L2A2 and would like to know how they were serialed. There's a 4-digit number (5777) scratched into the paint on the bottom of the objective lense tube. Would this be the serial number? Also, was a special tool used to emboss the number onto the label?

Thanks in advance!
