This was found in a loft. Made of mahogany wood. It can be carried flat and has lots of measurements and a spirit level. Wondering if this has something to do with measuring a projection of an object but no idea really.
Is this the same thing that's in this post: http://www.collectorsweekly.com/stories/171824-us-military-issued-tool?in=activity
It's an angle finder for roof pitch and the like.
It vary similar to a carpenters speed square but probably used for layout on large timbers.
