Bahamas Logotype


I am working on a critique of the Bahamas brand for a class. Any idea what typeface would be closest to the logo text itself (I know the main and sub-text are different). I'm afraid the "m" and the "s" might be custom, but I don't know that much yet :P


Some versions of Futura (Bitstream, Tilde, Scangraphic...) but you'd have to edit /m at least.
Alternatives: Backtalk BTN, Chalet London mixing 70 and 80 (but the /s is totally off...)
