It is my understanding that the Bell key code 1C was used by Keeney, Genco or perhaps United.  So I assume that 1C was a code shared by more than one manufacturer.

Please educate me if you know more concerning this code.

  The 5/8 inch locks were used primarily as coin box locks which attached to metal.  The longer 7/8, 9/8 and 11/8 inch locks were used on door or cabinet locations mounted on wood.

The distance from the inside edge of the front to the face of the cam is about 9/8 of one inch.

This is a good lock that works well with the original key that is included.
