oops sory david, fist time i have heard this question :
just noticed something on your brush pic billygoat,
where the black screw is, at the sides, we have them but they have 2 screws in each side, this stops the movment up and down, gaz Hh20 set them at a 45d angle, this way it only swivels left to right, and i think
it was basicly to help stop them breaking,
