At a time when four engine aircraft were still relatively rare, the Heron was well received by flight crews and by passengers who appreciated the additional safety when operating into more remote locations. Some 150 were built and exported to around 30 countries. Later, a number of Herons were fitted with 290 hp (216 kW) Lycoming IO-540 flat-six piston engines.The modifications were carried out by the Riley Turbostream Corporation of the USA and so became known as the Riley Heron. Due to clutter it was difficult to get a nice side on shot but this view shows the flat engine conversion nicely.

The Brantly B.2 first flew in 1953 and had a simplified the rotor head, with flapping hinges at the end of aerodynamically-faired stub arms that reduced vibration. The drive from the main gearbox did away with the usual rotor mast, resulting in a very low rotor disc and low centre of gravity and so reduced the risk of a roll-over during takeoff or landing. Improvements to the basic design eventually led to the B.2B, which introduced a new cockpit canopy, new metal rotor blades and an uprated fuel-injected 180 hp Lycoming piston engine. The production of both versions totalled 334 units.

This JetRanger was built in 1968 and used initially by the Försvarsmakten (The Swedish Armed Forces) and then by the Swedish Army. After being Struck Off Charge it was stored at Linköping - Malmen (ESCF) before becoming part of the Flygmuseum.

This AT-16 flew previously with the RCAF (as FE792) and then USAAF (as 42-12279) as it was assigned to the Swedish Air Attaché in Washington DC in 1947 before being TOC by the Flygvapnet in 1951/2 as as Sk 16A with serial 16144. It is pictured inside at the Flygmuseum but still flies on the warbird circuit during the summer.

Between 1954 and 1956, Saab manufactured 76 copies of the Spaningstunnan, the reconnaissance version. The S 29C was equipped with seven cameras but carried no armament. This aircraft was delivered to Södermanland's air fleet F 11 in Nyköping in March 1955. Four years later, the aircraft was transferred to Norrbotten's air flotilla F 21. For the last three years 1967 to 1970, the aircraft was stationed at Östgöta air flotilla F 3. it was SOC in June 1970 and is now on display at this very interesting museum.
