This is how they left the factory, which is more desirable than one that was substituted later.

You would have to go through 10,000 guns (into the next lettered block) before you would find one with a 92 on the outside of the trigger plate, and a 9 on the inside. This is the normal way they were marked by Mauser that year.

Yes - the approximate month can be estimated, but I don't have access to my reference book (The Mauser Parabellum) that lists the ones made that year.
