Theses rings (ring) press fit on top of the Whirl-A-Gig provided by my previous offering. I first saw these on Dave Garaway's popular 7 AM TV show c 1956, channel 4. Your eyes are likely to see the rings roll around each other by magic. Kinda fun.
There is a small pair and a larger pair of rings provided. Choose either one.
The author marked this model as their own original creation.
