Frigidaire coin laundry
When I was a kid in the 60's my grandmother had a house at the Jersey shore (Lavalette). There were several of these Frigidaire coin laundries up and down the main boulevard (Rt.35). The machines were always turquoise, had the round window and a very fast spin speed. I was fascinated by the Frigidaires because I never saw a "pulsating" agitator before. It was very cool. Of course I always wanted to go when she went and my dad would get very upset that I didn't want to stay back and play with the other kids. Check out the pic in Phil R's link above, looked very similar. What model machines were they at that time?
