The Crossley "Eagle"
and "Hawk" buses
The "Eagle" range of single and double deck buses was
introduced in mid 1928. The last were built in 1930 but still
appeared in catalogues until 1934. The "Hawk" was a shortened version
designed for the coach market.
82 forward control "Eagle" chassis were produced with numbers
90000 to 90080 and one normal control numbered 90101. Two were
built as double deckers and one was bodied as a van. Twelve "Hawks"
were produced numbered 90301 to 90312.
The remains of one Hawk survive.
