Thanks Robert / Unimatic.
SO ODD. I don't remember more than one Frigidaire product in this area, and that was a Frigidaire 1-18 washer in a summer home in Miller place (Suffolk County) L.I.
I did see Frigidaire brand in Rehoboth Beach, DE and Winston-Salem, NC. so I ASSUMED it was more southern.
Interestingly people's homes where I grew up (in a small area "suburb" outside of Flushing, Queens) came with a lot of WP. When those died lots of Sears KM came in. A spattering of Maytags and GE were around as well.
My earliest recollection of laundromats is mostly F/L wascomats and Philco-Bendix.
