I believe this pocket watch chain is from Europe as I found it attach to a patented size 18 sterling pocket. The watch is not for sale right at the moment but this chain is. The t bar and chain and hook all tested as sterling and is nicely marked inside the hook.It is marked sterling the chain is rather long length is about 12 inches on each end , on one side is a hook and the other is just a ring. I believe one of the hook was removed so that it can hold a winding key which is not for sale. The chain is very nice quality and weights in at around 22 grams of sterling silver. Pls let me know if you have any questions. Also see my other nice estate finds.
