This is not your average ruler!
Made from brass by Stanley London it has come from gentleman who worked in the maritime industry across the globe for over 30 years.
We belive it may have been used by marine architects or draftsmen.
Still in its original timber case it is a stunning piece, we are not likely to see one like this again.
Measures approx: Ruler-130cm long Case-135cm x 9cm x 4cm
