Thanks for all that info!!! now I just need to find a picture of that toilet.That was definitely a Universal Rundle. When my friends bought their house in 1984, they had one with the marbled glaze and the bucket tilt valve like in the pictures above. "Yours truly" got the job of cleaning it up and getting rid of all the scale that had built up under the rim; I guess you can say that this was the first toilet that I "restored". I also gave them a stern warning to keep it clean, and not allow it to get into the condition it was when they moved in.
In the 1960's, Universal Rundle made the "Sculptura" line for Sears, which included a one piece toilet and a two piece model with side handles (actually tried out a 2-piece in 1965 at the tender age of 10 -- it was green (before avocado green), and it was in Greenwich Connecticut, my father's home town). The sink also had the Sculptura faucets, which as I recall had square handles that you pulled forward.
"Homart" was also a Sears line made by Universal Rundle. They included the "economy model" with the trap at the front of the bowl with a jet that shot out a flat sheet of water, and the "good" model reverse trap toilet which had a large rectangular "mouth" in the bottom of the bowl that resembled a tunnel entrance and was described in their catalog as "neater in appearance than ordinary washdown toilets with trap in bulge at front".
In the late '80s and '90, you could find the Universal Rundle Atlas that was also sold as the Sears, and featured in 1990's Consumer Reports as one of the two best 1.6 toilets of the time (I had one of those too for a while and went back to reconditioned 5 gallon toilets until finally replacing them with the 1.6 Drake and Cadet 3).
In 1997, my next door neighbor moved and took his toilet with him (a 1957 Mansfield with the trap to the front, which he installed in his master bedroom replacing a Mansfield ADA height toilet which he hated. That bathroom had once had a Universal Rundle toilet with the marble glaze, and they had it stored in their garage because they were going to eventually install it at their camp. They also removed the remaining 2 Universal Rundle toilets (harvest yellow and washed out blue) and replaced them with early 1960's Eljer toilets that I had refurbished.
He took the Borg-Warner 5 gallon economy model with "Whirlpool Flush" that had been removed from his office building, cleaned it up, and installed it in his condo a week or two before he moved. It's still there now, and the newest owners of the condo use it a lot, especially in the evening. It seems to flush at least 8 times an hour, possibly related to the unusual quantity of wine-in-a-box containers that I see in their recycle bin on Fridays. I would hate to be paying their water bill, which will be high. By the way, Borg-Warner sold their plumbing line which became Artesian, and then Artesian was bought out by Crane.
So, there you have a little more toilet history and a little trivia that you can enjoy and learn from!
