I have a set of of Bramptons from Ray. A work of art. The only "adjustment" I had to make was to smooth the radius on the indents of the damper knob, they were a bit sharp and felt uncomfortable to the touch. Mind you, I had to be very, very patient. I know Mike has said he is making them but I placed an order at the 2010 International and have heard nothing since. When I get my old (original) Bramptons straightened I will decide whether to sell them, sell the new set or fit one to my Comet and have 3 Brampton Vincents plus a set of Girdraulics hanging on the wall.
