UNCOMMON RABONE NO. 1179 COMBINATION PROTRACTOR FOLD RULE - 3FT 4 FOLD

Seldom seen longer model that features a protractor on the interior of narrow boxwood & brass rule. Fine overall condition noting a slight skew in the boxwood and a pin missing. Interestingly features one bevelled side on the interior outer edge. I could only find one mention of it in their catalogues.
