Hello
I noticed your question today on the internet and wanted to leave you a reply, so i registered quickly.
I guess your paperweight, also called porte-perruque (witch isn't really a wig stand), is from Belgium origin. I have a few of them in my collection similar to yours and they come from Verrerie Herbatte near the city Namur or Namen in south belgium. Occasionaly they can be found for sale, and even rarer they come as a pair. If they are not marked, it almost isn't possible to find the exact maker. Often the come with the pontil- or gadget mark on top, and underneath the foot as a Y or T. They date from around 1900.
