The Saab 91 Safir first flew in 1945 and was designed by A J Andersson who previously designed the Bücker Bü 181 Bestmann and therefore has some similarities. It saw service as a trainer (Sk 50) and as a liaison aircraft (Tp 91) in the Swedish Air Force from 1949 until 1993. Ethiopia, Finland, Japan, Norway, Tunisia and Austria also bought Safir for their Air Forces. The Safir became popular in civilian use and have been used in many places over the world.
Here are pictures of four Swedish planes, two at Västerås Flygmuseum, Västerås, Sweden and two at Aeroseum, Gothenburg, Sweden. The two at Aeroseum are photographed during maintenance but all four are in flying condition! The last one is the only flying Saab 91A Safir, it has a de Havilland Gipsy Major engine as opposed to the six and four cylinder Lycoming engines used in the later models.
The only available kit at the moment is the SAAB 91 B/C/D Safir from Tarangus. It's a reasonably good kit, you can read my review of the kit here. It has decals from the Swedish, Ethiopian and Finnish air forces.
