I've always assumed the H&H Climax action was a variant of Scott's "Triplex" action. The "Triplex" was used on many gunmakers' guns including my 1886 Reilly 16 bore (shown with Diggory's hand) (there is a Scott patent use number on the gun but otherwise no Scott markings).

Holland and Holland advertised the "Triplex Action" it in the early 1880's:

Gunman explained what the "Climax"action was all about and how H&H modified. Here is a 16 ga H&H Climax action which to my uneducated eyes sure looks similar to the "Triplex" right down to the crystal cocking Indicator.
