Tool?
I really have no idea what this is.
This is also one of the many items which were in a keepsake box, which had belonged to my late father or his Uncle...my Great Uncle.

You have an antique parallel ruler. People don't use them anymore. Nice item.
FYI: People still use them, I just saw them yesterday in the drafting supplies isle at the office supple store. ;)

I still use them for layout but very few people even know what they are or how to use them.
I am waiting for Mercer to post a pantograph because I use the two together.
These look like they maybe for ship board navigation, pre -gps. I have a set I still use occasionally drafting 3 dimensional plans.
As my father was in the Navy during the war, I suppose he could have used it then. Although he was a Radio Man not a navigator. He did however have a boat and did chart course on maps.
Thank you all for all supplied information.
