Agitator
Dave----While there are some broken-away bits off that agitator, it's truly average/normal for this machine. Sand or file rough edges and go to town! The filter holder is in place, check along both sides to see if chunks are missing or if the full bottom width exists along its entire 3 or 4 inches. Often the breaks along it allowed the filter to fall and break the cones. Very routine and still very usable with either no filter, or a filter holder replaced..
I can read REGULAR and PERMA PRESS on the timer, what's the third section?
You aren't familiar with 1-18 action?? You are in for a treat. Loud and excellent turnover, great rinsing. The spin starts at slow speed, does a spin drain for two minutes, then kicks up to high-speed a bit before spraying begins. And wait until you see the circle of spray, it's thorough and complete. Then the spin stops while spraying continues for the rinse fill. Pretty unique behavior in a few ways. Let me check my basement, I may have a spare fabric softener dispenser to make your set-up complete(r). I believe the bleach dispenser was a rarely purchased option. Otherwise, it looks like you have 2 speeds and three cycles, that covers all the bases.
One of these days I want a 60's solid tub GM Frigidaire, see how the heck they work.
