Hello
I was in Paris last week and I remember that few ones were available at the bookshop "La maison du Livre d'Aviation" ,
http://www.livre-aviation.com/.
Contact them . I think you can pay online , but I never try it .
Concerning the quantity of fw 190D-11 , we have evidences that W.Nr 220017 flew , so we can say circa 20 machines at least were built .
Concerning Fw 190D-13 it is the same there are evicences that W.nr 836017 was used , so the same conclusion can be done .
Fw 190D-12 except prototypes we have no evidence that the production was launched .
All the best
Eric
