I don't believe solid tub, if I am correct, solid tubs all had the side opening lid, I had probably the last solid tub with this style/buttons control panel and that was a 1974-77ish, I bought them used in 1980, after that they went with a perforated tub and the rear opening lid....
others may have more exact facts
still a nice set just the same, a little high price though
I'm pretty sure solid tubs were made up through 1980.
I havent seen a solid tub for sale locally or even at the dump
for about 20yrs,so seem kinda rare these days...
The washer pictured somehow looks slightly older than the 1984
SQs i have,so might be 1981-82?
It's a perforated tub model. The giveaway is the ridge around the top. The solid tub models had a totally flat top, but when they switched to perf tubs, the top gained the ridge.
Its a perforated basket machine. The last of the solid tub machines are rare mid 1970s through about 1980, when they added the brake to them they had major problems with the drive line. The last of the ST machines also had a larger tub, I remember how disappointed many customers were with these washers when they had major breakdowns in the first 5 years we scraped many of them in less than 5 years.
