I don't know if this brush has ever been used.  It came from an out of business shave shop, where it was a display item.  I've been shaving for over 50 years, and I've never seen an angled brush before.  It is branded "LIWA widax, vulcanized sterilized".  It looks to have a 19 - 20 mm knot, that doesn't seem to shed.  That's all I know about it.  Bidding starts at 99¢ with $8 shipping CONUS.  Thank you for looking.  Good tidings and good cheer.
