Richard,
 
British Archaeology Reports' series - The Archaeology of the Clay
Tobacco Pipe - is a useful source.  I think Peter Davey is the general
editor and they even devoted a single volume specifically to the
Glasgow industry (I don't have the citation in front of me)  I've run
across a few surviving catalogues from the period your period as well -
if you hit a brick wall, drop me a line through regular e-mail and I'll
try to help.
