hotsell Antique hydrometer set by Taylor Instrument Companies, set is unfortunately missing one piece. However set is in good condition, box does show some damage please view pictures.

According to my research I believe this set to be late 1800s or early 1900s. please view pictures to determine.

Dimensions of case are approximately 15" x 6.25" x 2.5"
