It was an attack against a CR.42 of 1/3. Fighter Squadron (not against a CR.32) which stationed at Annopol on that day. Since it was an insignificant event with no recorded damage, aircraft was not mentioned (and serial, markings are not known - actually the original documents not remained in that deep level from that squadron).
I mentioned the story in details in my 1/3. Fighter Squadron book on page 35.
