This was one of the coolest toys we had growing up, and I can't find out a single thing about it. It was called a Playall [Play All? Play-All? PlayAll?], which, in this CD and MP3 era, turns out to be a nearly Google-proof name.
Judging by the photos--that's my brother up top, my sister below--we got the PlayAll no later than 1973, and it was going strong in 1978. [It finally got left behind on a move because someone *ummm* cut the bottoms out of a few too many of those circular indentations on the side.]
It was made of super-thick, injection-molded plastic, and its three pieces locked together in a W-shape, a question mark-shape, or a full circle. When it was a circle you could roll a kid along inside it. Set on its side, the three pieces made a great fort.
For the shipping alone, I'd hate to buy one of these things on eBay; but at least if I knew what and where to look for, I could start preparing the UPS guy for the burden. Anyone?
update: we have one lead: the Edu-Ring, by St Louis-based Learning Products, a long-time maker of plastic educational toys and furniture. Any more tips out there? {thanks, dt reader kate below]
I know we had one of these at the gymnastics school I used to go to. They probably had it there well through the 80s. Maybe gymnastics/school gym close outs/yard sales?
Looks fun. Never seen it, but maybe this will give you some more google words:

how about the Edu-Ring?
[hey! very much the same, but slightly different/updated. thanks -ed.]
The Gymboree Play and Learn Center here in Singapore has a couple of these. I'll examine it closely the next time I'm there to see if I can get a Manufacturer name.
There is one of these at my son's My Gym class here in California. I'll ask where they got it. It's newer colors and the gym isn't too old so it must be available somewhere.
They have these at Gymboree here in Houston. Someone must be making them.
