​I was contacted by B&B member BladeShark who has amassed quite a bit of information about Rubberset brushes. This thread is for B&B members to add to the collective knowledge in order to build a database of Rubberset history and brushes. This thread format has been gratuitously copied from the Ever Ready Brush thread started by SavantStrike (thank you) http://badgerandblade.com/vb/showthread.php/109533-Ever-ready-model-numbers-post-your-numbers-here Please read and digest all the information in this post so we don't end up with a ton of posts that have to be re written to include the data you didn't read about in this initial post . Then please start posting like mad with the following: -Information about Rubberset brushes you own/have seen -Pictures of said brushes if at all possible -Wild speculations about what all of the data being collected means -Personal stories about Rubberset Brushes -Shavegeekery Include all/some of the following information: -Model number (both digits and letters) i.e. 400-3 -Handle design (note that this may not always mean material, but it does mean quality) -Type and grade of hair used -Knot size -Loft height -Handle height -Total height (Loft + Handle) -Color -Some other information not yet known at the time of this post From the Wiki : http://wiki.badgerandblade.com/Rubberset The Rubberset company began making brushes around 1887 and began advertising around 1905 . Early advertising featured various attempts to pull the bristles out of a brush, or otherwise destroy it.
