just back from service (and much nicer than these "as bought" shots, I need to find my camera!),
1888 Model 1 Illinois railroad grade. its "coarse train" so it runs at 2hz (14400bph) and sounds like an idling diesel when you leave it on the desk. clunk..clunk..clunkity clunk clunk....
and yes, thats a winding & setting key sitting next to it.
