The Cessna 150 “Patroller” was introduced in 1960, and was an optional model until 1963.
The Patroller was a standard 150 with the following options:
--acrylic glass windows on the lower doors
(listed as "translucent doors" in '60, and "transparent doors" in '61, '62, and '63)
--38 gallon long range fuel tanks
(35 gallons usable)
--a message chute for dropping packages to the ground
("liaison communications" according to the '63 sales brochure).
Although "patrolling" is mentioned in the '66 brochure, the Patroller model and Partoller options are not mentioned after 1963.
