Nate, your description was right-on. An O'Keefe & Merrit labeled version of this design was in our house we bought fall of 1961--it got pulled out and sent to our old house since the Waste King was only about a year or so old and a far better dishwasher. Friends moved into a house in 1963 which had the same BOL as our house did, but had the Tapapn brand on it. Yes, it was very quiet. Was abysmall at anything cleaning. This BOL model didn't have separate racks. The top & bottom racks werre connected and you loaded through the opening in the top rack, thus capacity was horrible. The BOL timier had normal wash, short or light wash, rinse & hold, and plate warmer. The "cylinder" rotated during dry cycle to move air currents.
