Vulfix released the 90th anniversary brush and gave it an Astor handle.
Gary, We must know EVERYTHING!!
The KH stands for Key Hole (pretty obvious if you look at the handle shape!). The Duke's are actually named after Alex Simpson (it was his family nickname!). The old KR7 is named after the house that one of the staff lived in (7 Kents Row - in Somerset where the mill used to be). Wee Scot is actually not just after it's size but because of a name connected with the family. The X2 is one of the brushes named by my Grandfather - after my birth!
Have you bought an Astor brush recently? Within the last 10 years?
