A thought has come to my fevered mind! J.P. Dean was in the Twin Cities and probably the most notable gunsmith there in the 1890s to WW-I time frame was Frank Novotny --

Frank might be a good candidate for 79051's ejectors and single trigger.
I have a vague memory of some mention in
Parker Pages about Parker Bros. guns being shipped to Novotny for custom work. Anyone recall the issue or am I dreaming.
Our Home Page shows there is surviving material for a letter on 79051.
