Built at Zavod 31 in Gorki, this aircraft left the factory on 11 August 1942, and was - probably - assigned to 524th IAP as White 57. After a short period of service, 3121357 was damaged by the Finnish pilot Altto Tervo, during a combat over the Olonets isthmus on September 14th, 1942. Captured by Finnish forces after a forced landing in a meadow at Ala-Sedoksa, near Nurmoila, the aircraft was repaired by the Finns, and joined LeLv 32 as LG-3 in the end of 1942, flown by Warrant Officer E. Koskinen.
During the summer of 1944, LG-3 was slightly modified:
- The antenna mast was shortened;
- The tail wheel was made fixed, and its doors were locked in closed position;[N 1]
- The upper part of the yellow band on the nose was repainted olive green, to make it less evident from above.
After this modification the aircraft returned to service with HLeLv 11 on 4 December 1944. Last flight was on 29 January 1945.
- This could have been done because of the unreliability of the mechanism; the doors were slightly cut to fit the leg.
