This is a Polo handle from Rooney with a Boar Bristle knot. It's one of the finest, softest boar brushes I own.
Originally there must have been some form of insert in the base but now there is an old 1912 Englsh penny held in place with silicone. I will likely change that out for a grout base.
These two Classic shaped brushes were made for Brooks Brothers.
Three Miltary handle Rooney brushes. The one on the far right was made for the Boots Pharmacy chain.
This large size Persian Jar Super Badger brush was made for the Dunhill stores.
