This is a 1941 Waco UPF-7.
Waco is actually an acronym for the Weaver Aircraft Company. This
airplane was called the PT-14 in US military service. About 600 of
these were made and about 150 or so are still in existence today.
Although not as popular as the Stearman, they are still an important
part of the last era of biplanes.
