But if she can collect moose stuff, I can have my whatcamacallit.
As far as what it does, not much. The globe and the arrow shaft rotate in the stand. That's about it.
I had always thought these were some sort of primitive navigation device, like a sextant, and, as I said in my post, I thought it was called an astrolabe.
But after I did a Google search, this doesn't look like an astrolabe. Which is a navigation device.
An astrolabe is circular and has a movable arm on it like a clock face, or actually more like a circular slide rule. (If that doesn't date me, I don't know what does.)
I'm just curious, and thought that if anyone would know, it would be someone on FP.
