Yes,

If you look closely at the mechanism the manufacturer's  name is  
stamped into one of the parts "GAMEWELL" in  script.
Someplace I have the pen recorder that receives the codes.   This  
technology goes back to the 1800s.
However it was still in  use in the 1980s for troubleshooting dial  
pulses on trunk  circuits.
