Frank-what about ebay for this one? I'm not up on insulators but this looks like one that would do well there. Is it Tillotson? Any markings on it ?...John
If ya look close at the crown youll see the tilluson lightly embossed. Its a great threadless! I agree though i think ebay might be the right place for this guy.
have you thought about hecklers or glassworks? they only deal in top quality glass such as this.... i dont know if they do insulators though....ive never had any dealings with them...
