Good question! As a Pioneer factory rep from 1977 to 1996, I assembled at least two of these for Circuit City (one for a retail customer and one for a CC store) and, at least two or three for Best Products. One or two in a Best Products showroom and one for a customer of their's in the Tidewater area in Virginia. I was there for multiple hours doing the Tidewater assembly all by myself until later in the evening. The consumer left at lunch time to get something to eat yet never offered me a soda or anything during my long day at his house. He said it had to be completed by evening so I couldn't leave his house until it was done. I was just out of college maybe a year. He also insisted I install a keyed power on/off switch he had picked up so that the teenager in his house couldn't turn it on when he wasn't home. He's lucky I knew what I was doing because no one taught us how to do that prior to any install. He did make up for the lack of drink, snacks or food, though, by giving me a few very vintage and rare Pioneer brochures he had picked up many years ago when he was in the military! I still have them in my literature collection. "The Rack" was mainly used to display and demo Pioneer gear at store level but retail customers could buy a complete, outfitted rack from an authorized dealer, provided they came up with the dough to buy one! I believe the legs were added a bit after initial introduction due to liability concerns regarding any idiots who might lean (or sit on!) the protruding shelf holding the turntable. The Rack with all its gear mounted was quite heavy! The Best Products catalog from 1978 pictures "The Rack" on the inside last page of that catalog and it does not have legs. I believe any that were sold to retail consumers did come with the legs. Too long ago so I can't be certain. Retail cost to a potential customer involved adding up all the components at retail price and, if memory serves me correctly, the rack itself was "thrown in" for free. So was assembly by a young Pioneer rep like me! And my cheap boss never compensated me in any way for these extra "projects" in consumer's homes. Just part of my responsibilities he'd proclaim. I also worked on several more store level "Racks" when newer gear replaced older models over the next few years up until about 1980.
