Many thanks to Jim in Dallas who sent me this manual for the Foley 392 Power Setter.
I had a request for the Foley Model 200 manual. Foley had two model 200 machines. The old model 200 was a key copying machine. The newer model 200 was a saw filer. While I haven't used the model 200 saw filer, it looks a lot like the SF-1000 / newer 387. The manual for that is linked at the right. I'm guessing that Foley discontinued the name 'model 200' due to confusion of the two.
I'll write up the difference between the old & new filers soon, but as far as I can tell, there were essentially two different machines (old vs. new or grey vs. green) with six different model names (old: F-4, F-5, F-61, 387; new: 387, 200, SF-1000).
