Hi All,
Bought this on Sunday at Cheddar Car Boot, comes in a nice leather case which I have re saddle stitched.
Label n it said it was a "Roof Angle Measurer"
Certainly some sort of inclinometer but not sure whether is is missing a handle or mount of some sort.
There is is a half mirror inside that allows the spirit level bubble to be seen, almost like a sextant.


Any thoughts please?
Cheers, Martin
