I have a large amount of estate pipes, some high end some those drug store finds.
I think the Briar used years ago was older grown then what they cut and use today.
I also have new pipes from GIGI, Savinelli, Larenzitte, Peterson's ,Paronetti. Viking.
but my old Comoy's Blue Riband, Sunrise 495, GBD Valois 808 and all my old Kaywoodie's
are some of the first pipes I go for.
I think the old Briar was better. I'm not even sure that it all true with older pipes being of older growth.
but there has to be some true in that they made more pipes over 50 years ago then today. and the Briar bushes need 50+ years to grow to even make a pipe. maybe something to it?
