EZ 42 and Fw 190 D-9

[Schlageter]

I have two questions concerning Fw 190 D-9 equipped with the gyroscopic
gunsight EZ 42.
27 D-9 were built with this gunsight, 20 in February, and 7 in March 1945, according to JaPo's "Focke-Wulf fw 190 D camouflage and markings".
Were the EZ 42 distributed altogether to a certain manufacturer like Focke-Wulf or Fieseler, or were they dispatched to several production batches?
Which a/c are known to be equipped with the EZ 42?
I know only Barkhorn's Dora so far.

Thanks in advance

Michael
