Circa 1920-1930's technical drawing instrument set in velvet lined wooden case. Includes dividers, lead-holders, articulated pens, protractors and beam compass. The inlaid wood case is monogrammed with initials "A. D." on top and measures approximately 8" x 4 5/8" by 1"1/8". Two pieces of veneer are missing on edges of case. This would make an excellent addition to any Antique Science or Engineering Collection.
