I was able to fabricate a plate.
Does anyone have any pics of the clapper ?
Or possibly the pat. office info.
The cam is in the unit but the hammer is broken at the pivit and gone so I have no idea how the hammer mech worked. It has to be the chain type reset clock for the 850, the other bar type reset is a different clock, according to the pat drawings for the bar type reset clock.
1/3 of the original end plate was rusted away so if there was a spring on/in the plate (right)that held the hammer it is probably long gone.
Any pics or parts breakdown of the chain type clocks
