This paper describes the final incarnation of the Fermilab High Intens
ity Lab spectrometer which operated for ten years in the Proton West A
rea of Fermilab in the execution of two experiments (E537 and E705) wh
ich studied hadroproduction of high mass dimuon pairs. The version of
the spectrometer used in E771 differed from earlier versions of the sp
ectrometer by the addition of a silicon microstrip detector, pad chamb
ers and resistive plate counters. These additions were implemented to
give the spectrometer the capability of detection of secondary decay v
ertices from B --> mu or B --> J/psi --> mu mu decays. As discussed, t
he spectrometer in a short data taking period was able to address many
kinds of physics, other than beauty decays.
