Very nice antique gold filled watch chain with a T bar, dog clip and large decorative links measuring 5.6mm wide. The overall length with T bar is 11 3/4”. Wearable length is 11”. See last 2 pictures for how it can be extended with a brooch pin (not included) to make a beautiful necklace.
Marked WHH & Co. No other markings that I could find. It weighs 17.7 grams. This chain is in excellent condition for its age.
