How quickly can anthrax kill you?

Anthrax: The incubation period is usually 1 to 7 days for pulmonary anthrax. Per http://ideas.Health.Vic.Gov.Au/bluebook/anthrax.Asp “evidence from mass exposures indicates incubation periods up to 60 days are possible for pulmonary anthrax, related to delayed activation of inhaled spores.” incubation is followed by a somewhat mild prodromal phase with average duration of 2 days.
