If that "Maytag" sticker on the front is original---
Then, it is not too old compared with other BOL manual Maytags.
My memories of the "Blue Bell's" were that the Gyratator did not have a center-column. The metal Gyratotr depicted is placed so it is difficult to see whether or not it has a center-column. Also, the metal Gyratator throws me.
I am thinking if the Maytag sticker on the front is original, than the Gyratator would be plastic (1966 or later)?
Maybe this machine is much older, and the Maytag sticker itself is an add-on?
In any event, the non center-post Gyratator was a terrible clothes tangler, the worst I ever saw and this thing belongs on the front porch of "Coal Miner's Daughter".
Perhaps it was, given it's condition!
