Geotec Compass. The brand name almost sounds ahead of its time. But I bet it’s vintage.

It’s another borrowed item from Mr. O.P.

It’s been so long since I used one of these I had to google to remember the name. Not quite true, I had it right the first time, then I doubted that was it and thought it was a protractor (related of course) but then landed back on compass. Why is compass the same name for this tool and for a sea captain (or space captain)’s device?

This one had been sitting for so long it acquired a friend.

Status: Not mine to decide. Phew. It brought back good memories though. I like Math.
