I was lucky to snag this Replogle Reference Globe just as it was being put on the shelf.
It has a full Meridian on a wood-grained base, but I was a bit perplexed about the other ring around it with beads that slide. I searched high and low, but couldn't find a single one on the web like it. I finally asked for assistance, via a fantastic site for all things maps and globes. Murray Hudson is a major collector and store, if you are ever looking for a vintage piece for your collection.They were kind enough to send me a link of my exact globe model, and they had one in stock for sale.
Imagine my surprise when I found out it is a scarce globe, because it is uncommon to find this model with the ring still attached. It is an Orbit Ring, and is attached with clips on the meridian. The ring pivots at the clips, and the clips are movable. The bead on each side is meant to be a satellite, and you can slide them along the ring to demonstrate the satellite's path.
Ah, the simpler times. When a kid had that innocent sense of wonder, and could have fun with a bead on a globe.......
This model was first published in 1958 or '59, after the Sputnik Satellite mission. Based on my geographical research, this globe is from 1961 or '62. I am happy to say this globe is still vibrant in color and condition..........for being my age. :)
