The Maritime Incised Brass and Glass Compass with a foldable arc that works under glass is an antique reproduction piece that design likely dates back to the 17th century. Made from brass and glass, this compass features a sundial design, adding a unique and historical touch to its functionality. Crafted by an unknown maker, this compass is a perfect addition to any maritime collection, offering a glimpse into the navigational tools of the past. Engraved inside under glass, some lose dirt on glass, nice condition, patina. Estate find years ago. Thank you. Gnomon- shadow cast will indicate time.( Triangular piece)
