I now have two Falcons - one stamped "Made in England" in the standard aluminum finish and one in black that has only "Falcon" stamped on the bottom and a "4" stamped in the little inset on the bottom. A fair amount of difference in the draw on these two pipes. The black one (I assume made in the USA) is not as open a draw and I cannot remove the bit. Has anyone else noticed this difference? And is it normal that I cannot remove the bit? I like them both, but really like the more open draw of the one made in England.
