The hunt for pilot manuals continues. I found three new ones apart from the English made Bf 110 (probably a captured B-model) that was done through test pilot feedback.
Bf 109 G-6 pilot's manual - in English

Ju 88 A-1 to A-6 pilot's manual - in English

I found the manual for the Bf 110 B, with the Jumo 213 engines, but it is really huge, in German only and having such different engines + very different cockpit, it is not quite what the die hard 110 pilot wants.
Located a single page from the Bf 110 C pilot manual, and it has some useful and interesting figures related to flying the thing:
