From Laatokan Rannikkoprikaati's diary (SPK 17756):This is a rear thing indeed, not only at the Finnish front but itself - six were on Baltic and five on the Black Sea in June 1941. I don't have the book about sea recon biplane KOR-1 with me but IIRC this case took place in summer 1941 near Vyborg where those aircraft participated in recon flights and one made emergency landing on forest on enemy territory. IIRC only two from six were in service on Baltic in August 1941 already.
N:o 718, August 20th 1942, 6 p.m. [...] Enemy's single-engined floatplane have been found from Salmi's Sammallampi [= pond /Martti]. The plane is a biplane and intact, apart from some important parts have been removed [by the Soviets?].N:o 718 20.8.1942 klo 18.00.
[...] Salmin Sammalammin (x=6828, y=606) rannalta löydetty pakkolaskun tehnyt vihollisen yksimoottorinen vesitaso. Kone on kaksitasoinen ja on se ehjä, mutta joitakin tärkeitä osia on viety pois.
Here's is a map of the pond. This case is the only one I could find from a large list of captured and destroyed Soviet planes. It's quite clear to me the plane crashed probably in 1941 and was found a year later from quite remote spot.
