Not surprising that the listing is a Canadian auction - these compact GE sets were very popular here in the 1970s and 80s. The Condo Conversion Craze had not really taken off, so many apartments did not have hookups for a full-size laundry set. My second apartment in the mid 80s featured a Kenmore set - the dryer was stacked on a rack above the washer to save space.
This showed up today. I haven't seen one for years. I believe this is from the 70's. It has a single inlet valve and drain port since it was designed to hook up to a sink like a portable dishwasher.
Those little GE dryers left lint everywhere! Lynn and I had a set of these in our first apartment and lint was a real issue! Talk about lint and all the damp/warm air too! We had to run the ceiling exhaust fan every time we ran the dryer! And it was S L O W! But it was only 120! Greg
