Hello,My name isCustomerand I would love to help. There were no photo of the piece that came with your original inquiry. Please use the Add Files feature on your screen to add pictures of the mark on the bottom and of the caster.
I do not offer the phone service. I will answer without photos.
The mark of 800 on a caster means that it is made of 800 purity silver
and is not sterling silver which is 925 purity. These casters of 800 purity
were common for Italy and Germany from 1890 to 1910. This caster has a value of
$200 retail. To finish, I will need you to click the five stars at the top of your screen and hit the green submit button, thanks!
Please also add one photo of the caster ( I got the one of the mark).
It was a white box with nothing there.
