I am very busy tonight, so I'll try to put it briefly. This post is intended to everyone who miss discontinued SG snuffs too much to abide by the woeful circumstances. I am sure it is possible to bespeak any discontinued SG favourite. Such bespoke is possible in principle - the knowledge, skills, mill and recipes are still there. Thinking about obstacles, only unavailability of particular ingredients could preclude it technically (eg. a case of Bernard's Pariser No.2 discontinuation).
These are concrete SG bespoke precedents:
In 2015/2016 Samuel Gawith made a bespoken pipe tobacco blend for Dutch/Belgian Pipe Smokers forum (PRF).

It's a good and very informative read, really worth your time.
As far as I know, SG had made entire lines of bespoke snuffs for some online snuff vendors; ditto Gawith Hoggarth: https://www.fajkowo.pl/pl/p/Tabaka-Gawith-Hoggarth-Fajkowo-LE-2015-10g/7463
Bespoke, limited edition, unlabeled - whatever, I just need a massive amount of Blue Crest and Red Crest Scented.
