I took the time to go over all the brands (to the best of my knowledge/memory) I have purchased throughout the last 34 years and have to admit I am a bit shocked by the result.
Here it goes:
Briar
Savinelli (various basic lines, Punto Oro & Autograph)
Medico
Dr. Grabow
Paradis
Blatter & Blatter
Chacom
Butz - Choquin
Ropp
Lorenzetti
Frontenac (probably made by Chacom)
Stanwell
BBB
Viking
Duncan
Ben Wade
Hardcastle
Parker
John Brumfit
Falcon
Volkan
Rattray’s
Brigham
Alpascia Curvy
Peterson
The White Spot
Ser Jacopo
Radice
Castello
Winslow
GQ
BriarWorks
Neerup
Invicta
Briar (artisans)
Mark Tinsky
Pierre Morel
David Enrique
Chris Askwith
Ashton
Charl Goussard
Ryan Alden
Ian Walker (Northern Briars)
Ken Dederichs
Scottie Piersel
Claudio Cavicchi
Meerschaum
SMS
AKB
IMP
Unknown
Altinay
Sener
Morta
Mimmo Provenzano
Radice
And, of course, Cobs.
So, a lot of variety there that allowed me to learn about and experience various levels of quality. I have also learned that morta, meerschaum and cobs are not for me.
As of now, the brands I own (as mentioned in my introduction) are: Dunhill (all White Spots, ranging from production years 2014 to 2020), Peterson and Ashton. I used to have a lot more that what I own right now. But I am very satisfied with what I have, it works great for my needs a bit under 30).
In any case, I can't help wonder how long the list would be for those who own 300, 400, 500 pipes????
