Wood Grip Serial Numbers
 

I could not find this in the FAQ section, so forgive me if this question has already been answered.

Most of the time I see wood grips unnumbered or with the last two digits of the serial number only. Recently, I have come across some with all four serial numbers.

Is this characteristic of any particular model? One appeared to have a Simson eagle/6 stamp as well. Is this common to Simson lugers or Simson reworks?

My Simson has a 4 digit mark

That looks like the other two I have seen that way are Simson. One grip has 4 numbers and the other 2 .
