RIP John C. Loring! The "THE DUNHILL BRIAR PIPE - THE PATENT YEARS AND AFTER" has become my bible on dating Dunhill pipes. Some later corrections can be accessed at: http://www.loringpage.com/attpipes/bookupdate.html. Johns' book, by the way, is much more authoritative than the Dunhill dating guide given in Richard Carleton Hackers' "RARE SMOKE - THE ULTIMATE GUIDE TO PIPE COLLECTING". John C. Loring addressed a number of discrepancies in Hacker's book on his website which can be accessed at: http://www.loringpage.com/attpipes/hackerraresmokeerrata.html. I understand with Johns' passing, his estate is selling a number of his pipes, a collection that needs to be seen to be believed! I only wish I could afford them, but such is life. Long will there be another collector and scholar of Dunhill Pipes to replace John C. Loring.
