http://www.lespaulforum.com/pots/lpfpots.html There was a time when they did use 300K volumes and 100K tones, 300Ks starting around July 1973 and later 100K tones. In having looked at various Gibson pots, here's what I noticed in terms of part numbers and values:
44071079 - long shaft "tone" pot, 100K audio in very late 70s through mid 1980s, 500K audio in 1990s up until today
44070034 - long shaft "volume" pot, 300K linear
44070028 - short shaft "volume" pot, 300K linear
44070035 - short shaft "tone" pot, 500K audio
44070500 - short shaft pots, 500K, used in recent Historics, the pots with the scary plastic insides
