Me 109 canopy with slot at the top?!

Thanks Falcon! This confirms that the canopy had three sliding plexiglas panels: One on top and one each on the left and right hand side. This is consistent with the pictures I have compared with.
I get the impression that this feature can be found starting with the type of canopy introduced with the E-4 and then running with the F-series.

I have seen one picture where the top panel seems to have been opened, judging from the position of the "handle" piece.

Pressurized canopies do not seem to have this function which is quite understandable.

Later on the G-versions seem to have a fixed top panel instead of the sliding one???
