I am told that this was one of the last brushes to arrive at TGS before the Simpson hand over to Vulfix.
I would assume also that this brush is a Vulfix made brush only because Robert at TGS has said that Vulfix was making some of the brushes for Simpson even before the handover.
It may explain the taller loft.
A point of reference, this bush was apparently bought by an Englishman in the UK from TGS who never used it and was later sold to a gentleman in Australia, who never used it and sold it to another gentleman in the USA who never used it and now it is coming my way, to Tokyo Japan.
Quite a trip...but I guarantee that I am getting this one wet. No brush goes idol in my house. They all get a workout.
