Trurl Posted March 21, 2022 Share Posted March 21, 2022 Looks like a protractor to me. It is going from 0 to 90. It does have many scales but it just looks like it is made for a map. There are many things it would be able to do on a map. Like taking the scale on the map versus actual distance. That is my guess. What other pictures did the search engine show that were similar?
