Here are the a/c that it was installed in, FW-190A-8, FW-190D-9, D-11, ME-262, DO-335 and possible the TA-152.
I have seen pictures with it installed in the FW-190A-8, D-9, ME-262 DO-335.
I haven't seen any documentation of it being installed in the Bf-109. Due to the large size of the EZ42 it probably wouldn't have fit in the Bf-109.
Regards,
Mike
