I can't see either of your images. I'm getting an error message from Control Booth.

Now that @derekleffew has made it possible for me to see your photos, I'd say ours were similar but in my minds eye I'm remebering ours having their trimmers located to the right side of the circuit breaker rather than the left. Ours may also have had a white banana jack as well for conveniently plugging in you meter leads while doing your annual trimming. These would have been installed in Hamilton Place in Hamilton, Ontario, Canada during late 1972 when it was under construction for its planned opening in the spring of 1973 which failed to occur until September of 1973 due to construction delays. Thus, as @derekleffew suggested, ours may have predated yours by a year.
