Not a Delta, this was a full size machine, the Simpson equivalent was probably a 144.
The Malleys versions were generally more a posh version, weren't they? More features?
That dashboard looks like a Whirlpool design, grafted onto a Simpson machine.
Obviously intended to sell to previous Whirlpool customers.
Delta were a similar design but much smaller - the Delta was a cheaply developed machine, it was basically a Minimatic with a plastic extension on the wash basket to make it taller. Despite those humble origins, they were a pretty good machine, and IMHO tended to work better than the Minimatic they were based on.
There was also a later Delta based on the new Simpson design, which was more or less a copy of the Japanese machines that were taking sales.
