I picked this up recently as part of a shaving set I got at a church sale.
The brush is a Crabtree & Evelyn.
The sticker on the handle says "Pure Bristles"
and "Made in West Germany"
The brush, while new and unused, is probably from the 70's or 80's
I am guessing, since it is part of a shave set, that "Pure Bristles" means a mixed boar and badger hair brush.
I know there are some experts out there who can help.
