Very Rare Solid Silver Wrist Vesta 1903 Birmingham

Hi,
I have had this ultra rare vesta for some years now and i know it is very rare indeed, has anyone ever seen anyhting like it. It is solid silver and was made in Birmingham in 1903 by Matthew Wilcox & Son. On the front of the vesta were it opens it says Wilcoxs Patent. There is a matchstrike on the bracelet. Even the pieces that connect it to the leather are silver. This has not been made up. I forgot i had it till i started selling my silver and refound it. jonathan.slinn@sky.com
