You referring to 'Kriswill Blue?'The short answer is, no. Capstan's topping is what makes it distinctive, not the tobaccos. Find someone who has cracked Capstan's century + old topping and you'll find a match. It's available in 450G bulk packages at Esterval's, though currently sold out, however, the 50G tins are available for a LOT less than $20. The only risk is the occasional misfire with their shipping companies, DHL, or UPS. If that happens, you're going to get cornholed. Otherwise everything will be smooth sailing
That contains a small percentage of perique & is nothing like the original Wills's Capstan. (imo).
I saw that macbarens make a bespoke blend for a German tobacconist, they were given an old cutter top tin and asked to match it, that one's called' Bloemfontein'. How close they came, I'd love to know. I asked a forum member here who had a tin but didn't get a reply. Probably too busy taking selfies of himself on the golf course. Yes, @hoosierpipeguy I'm calling you out! Lol
As far as 'clones' to the original capstan go, there aren't any. That ship sailed many years ago. There are plenty of excellent modern day Virginia's though. Gawith's FVP & Mac Baren's HH Pure Virginia are up there with the best of them, only my opinion of course.
