This neck stock buckle was reproduced from the original buckle we own pictured on the top. The top dark buckle is not for sale. The original came from a Spanish ship wreck Nurtra Senora Del Rosrio that sank in 1753 of the coast of Mexico. The neck stock buckle we have made is just a little bigger than the original by 1/8" across the buckle. The measurements on the reproduction is 2" across by 1 1/2" tall. The buckle is made of solid brass and as you can see is adjustable. The buckle was worn with a linen stock or sometimes a leather stock and was worn under the shirt collar to make the collar stand up. The stock it self was made with button holes on each end of the stock to attach the buckle. (The stock is not included with the buckle.) We hope to list the stocks soon. The ship sank in 1753 so this buckle can be worn for those of you reenacting the French & Indian war and Revolutionary war time periods. You are buying one set. The picture is showing the front and back of the buckle.
