VDH Boar Knot Size?

[Pirate-M.Lifnen]

I've been searching all over looking for the knot size of the Van Der Hagen Boar/Surrey Shave Brush Deluxe to no avail. I assume there's only one size that they're selling in every supermarket and drug store.

Anyone happen to know it?
Thanks

Edit: Emailed VDH, it's 22 mm

hey did you ever replace the knot in that brush if so did it turn out to be a 22mm
