I don’t know if there was a pashtun balochistan per se, but yes there was there was the balochi-barohi state of kalat with a functioning assembly, and lasbela and makran were different divisions. Gawadar would probably go in makran, though back then it was part of oman.
Northern areas is a jumbled up state as well, where we had baltistan and gilgit with their separate identities. I don’t think NA is a full functional province even now.
