Vintage McDougall Ketcham retractable chain pin featuring an engraved engine-turned front and original pin-back construction.

Internal spring reel remains functional, with chain extending and retracting properly.

Reverse marked McDougall Ketcham.

Originally intended as a dress accessory, watch fob holder, lorgnette holder, or general utility chain reel.

A great piece of early mechanical menswear / personal accessory history.
