King George V Stamps - Not Mirror Image Left To Right Side.

Hi guys...Noticed on ALL King George V stamps that the crowns on either side are always different...The bars under the crown are different thickness's from left to right...The beads between the bars on the left are always more square and the beds on the left are always rectangular...And the distances between the lines are different from left to right..Just too much flyspecking...HAHA

Well, wert, you know these are pre-computer, Autocad and all that other good technology stuff. The human eye and hand, ask skilled as the engraver was, can only reproduce and image numerous times with a certain degree of accuracy.
Interestingly, I can only find the name of the engraver of the portrait, or vignette, mentioned in any of my books, Robert Savage of the American Banknote in New York. Though only a cursory look through, my Marler's, Unitrade and Billig's Canada War Tax book do not seem to mention the engraver of the border.
I'm sure more skilled investigators will enlighten us.
