Ah very nice and cool to get the chimney - most likely that one is made from bone! (and they are brittle, don't ask how i know...)
The 999 shape was every evolving. I have two pre-Republic 999's there are both different in shape and size. The 999 then evolved into the XL999, which returned to a chunky profile for a period and then to the slim 999 we know today. It makes you wonder how much of the pipe was made by hand vs machine?

For contrast, an early 1960's 999, Rocky Donegal.
