Thought this was a cool piece so wanted to share with you
It was being sold as a paper roll holder (?) but after researching found it was actually used by copyist's back when documents were copied by hand
There is a patent date on the brass knob
May 13 1873
I searched and found actual patent number > US138877
I have attached a copy of the patent as well .
Anyone seen one of these b4 ?
And yes, I did buy it ( couldn't resist )
