FINE EARLY UNUSUAL #25 MAHOGANY PLUMB AND LEVEL

Untouched. Will glow with a light cleaning. Uncommon variation with the slotted 'window' vial openings. Stamped '25' on one end. Not maker marked that I can see. This one is in excellent condition with some traces of original lacquer still present on some of the wood and brass. All 3 bubbles intact. 29 1/2" in length.
