help reaserching this luger

[MFC]

Hi Kevin,
The last two or three digits of the serial number 702 or 02 should be on the bottom edge of the takedown lever and sideplate, trigger , bottom side of the center toggle, rear toggle under the rear sight, grips, left side of the breechblock, and on the bottom of the receiver and receiver lug.
Very nice early Luger. Thanks for posting.
