Looking to see if anyone knows of a replacement for this timer (pics below) .. no real markings on it except for a handwritten label, was installed in 1993 according to the sharpie written note! Looks like 8 terminals on each side - 2 terminals for 24v ac, 2 for n.o. switch, then 6 inputs (a-f). Looks like an old Keltner timer, wondering if any of you more mechanically inclined guys know of a replacement? Thanks
