Reply to "confused about 761 sephamore"

Okay, took it apart a second time, the long rod running up to the flag has a round weight on it that slips on and sits inside the housing.  There's a copper contact that that linkage 1) gets attracted to when the rod is down (red), in the other condition the coil pulls the linkage "over" and away from the copper tab.  Playing with the tab and slightly bending the plunger ALMOST fixed it, note in the picture a curious trianglular strip of missing paint? It would go nicely into green "up" mode most of the time, BUT if you place your fingernail flush against the edge where the sephemore rides to limit it, it fires reliably. I surmise someone taped something along this edge to act like my fingernail and that's how this baby worked in the old days.  I'll have to figure something out and paint it black.  I love how the colored lenses look -

This is pretty much how I operated as an engineer - if someone knows about the problem already I want to know how they fixed it.  If I'm on my own, then I'll figure it out and share the answer.    Finis.
