The Finnish Defence Ministry bought 12 Gnats in October 1956 and allocated serials GN-101 to 110 for the fighters, and GN-112 and 113 for the photoreconnaissance versions. The planes were allocated to Hävittäjälentolaivue 11 based at Jyväskylä (EFJY). Despite the Gnat's positive features, it was a new and untried aircraft with deficiencies and design flaws. Unfortunately, it was troublesome in service, demanding repairs, modifications and technical issues that required constant attention. Four of the twelve were lost in service but this example is now a nice gate guardian at this super museum.

This C-47A was built at Oklahoma City and Taken on Charge with the USAAF as 43-48254. In October 1947 the plane started flying with Aero O/Y (the forerunner to Finnair) as OH-LCF 'Kyytipoika'. Its military career resumed in February 1960 when it went to the Finnish AF as DO-4. The plane was earmaked for preservation and by May 1982 became part of the (predecessor museum to the) Suomen Ilmavoimamuseo.

In June, 1942 this plane along with 7 other B-239s engaged 10 Soviet Hurricanes. The pilot, Lt. Pekuri, shot down two Hurricanes but his damaged plane crashed on Lake Big Kolejärvi, near Segezha, Russia and sank. Lt. Pekuri survived and in 1950 became the first Finnish pilot to exceed the speed of sound. After an undertaking by the National Museum of Naval Aviation in Pensacola, Florida the wreck was rediscovered in 1998 and recovered. Since 2009, the aircraft, as the world's only surviving Brewster, has been on loan to the Suomen Ilmavoimamuseo where it is preserved in its battle damaged state.

Swedish count Eric von Rosen gave the Finnish White government its second aircraft, a Thulin Typ D. The von Rosen aircraft received the designation F.1. The F.1 aircraft was destroyed in an accident which killed its crew, not long after it had been handed over to the Finns.

This was registered 1939-06-17 as OH-JÄMI 3, and was reregistered later as OH-WAB and finally OH-133. It was cancelled 1978-04-03 as withdrawn from use. It is painted here again with its former registration OH-WAB. This is the only still existing Weihe from the original production by Schweyer. It was modified with a new fully-blown canopy, and a shortened skid with a fixed wheel.
