Anyone Know What This Is? (Early 20th C. Electro-Mechanical gizmo)
 

I suspect it had something to do with the telegraph. There's a tag, but it's too corroded to read. The lettering on the glass case is highly stylized, seems to say 'Nun Co'. One of the coils says 'Struthers Dunn Inc. Philadelphia.' "Coil: 2A 60CY" "ContactsV110 AC"
The six posts are part of a circuit on the bottom, it doesn't look as though the two missing posts ever connected to anything.
Anyway, thanks for any help you can give.

A relay of somekind?

You can always ask them: Manufacturer of High Quality Relays & Controls - Struthers-Dunn

looks like some kind of telegraph repeater.

I'll give you $20 for it

A little cyber-shopping for the missuss' Christmas present, Lube?;)

Looks like two relays in a glass case. What does the circuit look like?

A search of dunco relays comes up with parts but no company history.

Just a (revised) guess...
It appears that DunCo is the retail "brand" of the Struthers Dunn Company.

I have an itching to make a steampunk smartphone with that...

Definately some kind of dual action relay. Looks like the stuff we used to have on our old power boards back when I started. I have tons of new S-D. relays in all my swithgear transfer feeders.
