I put this together as a handy one-pager. It doesn't have all of them, but most of the biggies, and a little history at the top.

Thanks for the chart.

The design identified as a Panoptic (1955) according to your link is by Kohler though Bertele has patents on a very similar layout from 1951 which may predate it.

It's not exactly a Nagler Panoptic, though Nagler may have based his design off of it based on his patent for the Widefield.
