Looking very good there Wayne. I notice the small ETC switch panel is fitted to the bottom of the engine instruments panel. Are you sure this was fitted at this period?
It's normally only fitted to those aircraft fitted for bombs, such as the E4/B and E7 (the latter as standard), and had the switches and circuits for the bomb selector/arming, and drop tank.
I'd have to check to be certain, but as far as I remember, the first use of '109s for bomb carrying was not until mid to late October, with E4/Bs, and certainly JG53 were employed in this role, with, eventually, a fourth Staffel being formed, I think for each Gruppe, as a Schlagtstaffel, and then these formed into a fourth (schlagt) Gruppe.
