Together with the second stock aircraft PH-ASX (c/n 5203) it was sold to the Swedish Count Carl Gustav von Rosen in January 1940, who donated them to the Finnish AF. Registered OH-MVF and OH-MVG they were flown to Finland were they received the s/n KO-129 and KO-130.

The two aircraft saw action in the Finnish-Russian "Winter" war (cease-fire in March 1940), and in the continuation of the hostilities (restarted June 1941).
