Gougler keyless lock

I came across an old Gougler keyless lock (made in Kent, Ohio) that was once used at the BF Goodrich Company where my father worked. It has a serial number of C654 engraved on the back. Above the Gougler logo on the rear of the lock another number was engraved, probably by BFG. This second number is heavily buffed over but I believe it reads A7040. Could anyone help me in determining what the combination to this lock may be?

The lock is round with a red dot in the middle of the dial.
