Just an Architect with a Question
I am here for a very specific reason and I am hoping someone can help. I am looking to identify the use of an old Proportional compass which was made in the U.K. back in 1920. It has scales in feet, chains, and miles. I am not sure where best to post a question wit photos about getting more specific information on it's use. As an architect I have used these for drafting, but this is something outside of my normal drafting sphere.
Any help would be appreciate.
