This rare beauty came to me in a box of brushes from a storage auction. The GFT I.B. 11 were made by Vulfux and only sold thru Trumper and at the Curzon Street location. They were designed to the dimensions & shape by than owner of GFT, Mr Ivan Bersch, his initials are in the model number. There were three other models, I.B. 6, 8, and 10. The knot on this brush is 32 x 60 mm with a overall height of 120mm. The knot is uber soft, very dense so not to floppy. The handle is very comfortable with a heavy size to weight ratio. A joy to use.
