Help with identifying the markings on this Bf-109

[13starsinax]

I would appreciate the forums insight on the markings of this Bf-109. I will try to post the zoomed in version, and the entire photo for as much context as possible. They are pulling the engine from the a-frame. There is a lot going on in this photo.

Is it a Technical Officer marking with a Geschwader Adjuttant marking over it? When was this marking common, and are there other examples?

I am trying hard to broaden my learning, and this forum is amazingly sharp.

Kind regards,

PS: I applied water stamps
