The electros for the Food Production stamps were created electrolytically from the Master Plate so there were no individual cliches.

That's true for the more modern stamps, but L and R are used to denote Left and Right all through the KGV era in the definition of location in exactly the same situation.
Sorry, I could go on all day on the issue of standardization - a by-product of my time at UPU and CCITT.
