Hi- My first question: I have a Graflex 3A in good condition. I've looked very diligently, but cannot find the serial number. It is not on the underside of the top door, a hint I saw someplace. I'd like to know the approximate age of the camera. It does not have the Autographic feature, so pre-1915. Help! Steve Fry

On my pre-autographic 3A the serial number is on the edge of the body that is revealed when the viewfinder lid is opened.

There were two 3A models before the final autographic.
Do you know whether yours is the first or second?
Relevant re dating and serial number location.

Mine would be the second model, since it lacks the corner cutouts on the bottom that identify the first model.

On my second model the serial number is on the inside of
the front door - between the tracks and close to the hinge.
This model was made from 1912 - 1915.
(serial number is 35158)
