6926 Mobile Recovery Vehicle is a Classic Space set released in 1986. It contains a large ground vehicle manned by two Classic Space astronauts (both yellow).
The vehicle consists of three seperate components. A detachable cockpit at the front, a lab module at the rear and a four-wheeled frame on which the two segments are mounted on. This structure is similar to 6892 Modular Space Transport from the same year.
The detachable lab contains tools and an appliance fixed to the wall, which could be a microscope.
