Hello!
My understanding is that there was 4 Hs 239s launched from 2 Fw 200s.
According this article in Finnish (which incorrectly claims Finnish AAA unit diaries do not mention the launching) one of the missiles exploded on land and one missile was found and destroyed in 1990's:
Ilmatorjunta -magazine (Anti Aircraft) 2/2016, page 28/64:
Precision bombs in Tornio 1944 by Ahti Lappi

One can copy and paste the text on translator.
Cheers,
