Hi Pilot
According to Jerry Crandall, there are at least two known Doras that were fitted with the wooden landing flaps, these being Fw 190 D-9 "Red 13" (W.Nr. 213 240) and Fw 190 D-13 "Yellow 10" (W.Nr. 830 017). There are a number of quite nice photographs of the landing flaps of the latter aircraft at the links below.

I have read that a number of Doras of JG 6 were also fitted with the wooden flaps so if you can come across any photographs of these aircraft there is a good possibility they had them as well. For what I have read they were quite unpopular as they quickly deteriorated in the winter weather. I hope this helps.
Horrido!
