Old silver watch chain with "square" links and oblong patterned links. Not hallmarked but sure it is silver.
The chain has been adapted at some point during its life and what appear to be brass fasteners added at either end. These could be quite easily removed. The chain is approx 10 inches long.
This is another piece of jewellery I am selling which I came across when clearing my parents' effects.
Thanks for looking and happy bidding. Any questions please ask.
