That's the lowest of the BOL. A neighbor kid I grew up with, in the late 1970s he & his wife bought this model. It didn't even have a heating element in the bottom of it.
I took a never used one of these a few years ago and combined with a tried TOL all push button MT RR DW to make the one in our museum, the DW tank even has the holes for the heater element, This DW would be great for parts.
