Original Hand Retaining Pin for Seth Thomas Antique Clocks

It is common to use a tapered pin to secure the hands on American antique clocks. Seth Thomas, however, originally used a straight pin with a pointed end to secure the hands on many of their clocks. Here are photos of the original pins, washers and hands to a Seth Thomas Adamantine mantel clock made in 1902.

The pin is 1.3 milimeter diameter steel wire with one pointed end, 9.5 mm long. It has 2 (sometimes 3) convex steel washers with square holes, 8.15 mm diameter, .3 mm thick, domed to 1.1 mm high.

Most antique clocks don’t have their original hand retaining pin, but I seen many Seth Thomas clocks over the years with pins and washers like those shown here.
