EARLY & UNUSUAL 'DOMINO' BRAND 2' STEEL SINGLE FOLD RULE WITH BRASS CATCH

No references to this rule company that I could find online and this is the first time I have seen it. Clearly marked as per above. I believe this may be a blacksmiths rule. Very early based on every feature including font, hinge, and brass 'catch'. Excellent overall condition and brighter than the pictures show.
