There seem to exist more shots of the same aircraft at Kassel-Rothwesten. A Me109 G-14 with Erla canopy?
Picture 1
Picture 2
I'm not fully convinced that all pictures show the same aircraft: the triangular marking above the "2" is visible in
M
MIflyer 's second picture, but not on the one posted by @Wurger .
Though the building in the background appears to be identical with Picture 1.
No fuselage band in front of the tail, so unit identification will become tricky.
The light horizontal area on the tail section indicates for me either a preparation for or an oversprayed horizontal bar.
Yellow colour: 3rd Staffel within Group
Horizontal Bar: 2nd Group of Unit
--> 12th aircraft assigned to 6th Staffel of (yet) unknown Fighter Unit
The Fieseler Flugzeugwerke are reported to have a small manufacturing line for Me109's at
Kassel-Rothwesten / Waldau at the end of the war.
Maybe this aircraft was a left-over and never fully finished...
