My very limited knowledge on this subject suggests the Finns operated approximately 76 Morane, of which 11 were MS 410s with fixed radiator, and 3 were converted to the LAGG-Morane configuration also with a fixed radiator. The rest were standard ex-French types.
Most of the images ive seen of Moranes operating in the cold winter conditions are with the radiator in the up position, But in the Summer its the other way round.
Dunno if this helps at all...
