What do you know

I recently purchased a 1906 30cal. Luger. Serial number 25143 all matching numbers. Says Germany under serial number. This is not a collectors piece but is in good mechanical condition and no rust. Above the camber it looks like there was a design, very faint either lost with age or buffing. Can one tell from serial number anything about this Luger? Thank you.
