Ketcham McDougall started business in 1875 anc continued in business until 2003 in New Jersey. This is an early retractable brooch with a C clasp closure. There pieces were made for ladies so that they could carry a small pocket watch, mechanical pencil,eyeglasses or other items for every day use. This piece is silver tone with machine age turnings. The chain works well. Size is 1 inch in diameter. The chain will extend 15 inches. This brooch would be excellent for a unique ID holder. Very good condition with slight finish loss on the reverse only.
