I used to deal with Jim Collette years ago - I know he passed away, very sad. I was looking for older Otis basement drum schematics, controller models: HKB, HKS, SOB, AP, 3F, 6F, as well as a controller print for a 3 stop Sedgwick roped hydro from 1990 that has an Omron PLC. Jim used to charge by the sheet - Really appreciate any help with this !!!
Sincerely,
Uncle Robby
