I have four (4) custom S-link livery collars (or Chains of State) for sale. These are not my usual S-link and they will not be produced any further. I am offering them to you for half of what I would normally charged for a collar of this sort. Each collar can be had for $100 plus postage ($5 in the lower 48 states.) Each chain is 27 inches long and made up of 40 individual S-links each joined to the others with small chain rings. This is sized very closely to the original surviving collar of S-links in the Victoria and Albert Museum.
These collars of Ss started in the later 14th century. By the late 15th century they had become strongly associated with the house of Lancaster in England. They were still in use in the 16th century and continue in use today.
The small link chains I make are based on those from the late 14th and early 15th century.
