I've got two questions; Are there extended needle valves avail for the monoblocks? I've seen them for the concentrics but not for the monoblocks and the needles are difficult to get to. I want to repaint my Atlas tank with the red that was offered in 1965 and I have read that the Yamaha Brilliant red sprayed over a white base comes very close. Has anyone had the the red matched or possibly has a sample of the color on a small panel that I could borrow to match the color? Thanks Dave
