'Cessna Aircraft Company entered the military utility aircraft market with a four-place jet, unveiled at closed showing to military officials on September 28, 1959.
The aircraft, designated the Model 407, was a sleek, low-wing, pressurized jet. "It is designed to fulfill military needs for a multi-mission, low-cost jet," according to Dwane L. Wallace, Cessna President at the time.'
A quick Google on PH's suggestion shows the above blurb (plus quite a bit more- interesting reading) and a copy of the cockpit pic is also on the same site.
