C&D Caps Blend question

[rdoss16]

tried this one for the first time and really enjoyed it. Tin note isnt great but once I started smoking it i fell in love. Doesnt seem to have great ratings but to each his own. my question is in the description C&D says "remarkably similar to one of the world's most popular pipe tobaccos" i assume theyre talking about Captain Black, but which Captain Black blend specifically was this modeled after? thanks in advance!
