First off Foley folded up shop awhile back. For that model there was an attachment for sharpening chains. Its primary purpose was for steel plate saws not the carbide tipped ones Foley and Belsaw split into 2 different companies many years ago. I am not sure if Belsaw is still operating either. there is a company in WI that has a few parts OEM old stock
The old Foley stuff was pretty light duty stuff at best. That said if you have really repeatable "touch" you can sorta nurse them along and do relatively accurate work. They feel a lot like a Oregon chain grinder.
been using the same set of Foley Carbide grinders for more than 40 years now, rebuilt them a couple times, rails and bearings.
