Here is another unique brush, and the first one that I have come across in fairly good condition. The Rubberset 'Pure badger' is one of the newer models that was produced as it had a badger knot rather than boar, the latter being the most used medium in earlier times.
Canadian-made Rubbersets had no model numbers, making dating this dame even more dufficult. Knotted with a 20 mm synthetic knot.
It stands 103 mm high, has a 56 mm loft, a waist of 23 mm and a foot of 34 mm. The brush weighs 54 grams.
