Ha, finally a question I can sorta answer... You aren't being ignored, our most knowledgeable meer guy (IMO anyway) has apparently taken a break from the board...
Unless it is 'signed' in the pipe itself by a 'master carver', or made by a meer pipe house (SMS, IMP ) who usually put their nomenclature on the stem, you are stuck with tons of uncertainty as to who actually produced the pipe.. Looking on the case is a good place to start, but if there's nothing there you are relegated to hunting the web for matching pics and making an educated guess.. The situation is far from clear cut especially when considering how many carvers copy each others designs,
