Thanks Bob.

From my notes on the master cylinders it looks like Bendix started stamping the date codes in the sides starting in 1969 as well as the manufacturing information.  That may explain why some of the original earlier master cylinders have no stampings on them at all.  Date codes would be in a Julian calendar format on the side, just like they were using on the bottom.  Bottom of the master is the casting date and the side is the assembly date.
