I think that NHS and Neville’s skunk should be mentioned if you want to try to breed it back, they both have some interesting skunk dna.
I also think that diesel and og/tk hold some old school skunk genes.
I think it’s very possible that Dave Watson just had bagseed. Maybe skunk was an heirloom bred in Mexico from Mexican and Afghan lines, his ohaze is Columbian bagseed, and what he sold Nevil was a rare Thai he thought wouldn’t sprout.
I spent years collecting and growing out Mexican bagseed (not the pretendica but the last of the Mexican when it was going away for me) and I used to think that there were lots of skunk genes that had gotten in there, but then I came to question Dave Watson more and my own nationalistic and racial biases, and it’s just as possible the skunk was in the Mexican bags first.
As far as ancient skunk archetypes, I definitely know that old forms come back, and I would love to see they are even older! But who knows?
An f2/s1 of Nevilles skunk or NHS or crossing them might show some serious old school skunks, and crossing them to your list pdizzle would be a neat attempt imo
