Wayne Terry, I'm combining my reply to you both, as you both seem to be broadly in agreement.
Terry, thank you for that definite reference about the open spinner. I am reluctant to put more work on you, as I appreciate you contribute to most threads on this forum, but can you remember if in that film footage the rudder and victory bars were shown? That would really be a clincher if they were.
Wayne, in my research back through Najco's 'Galland's Bf 109s' thread, both yourself and Flavio seemed the most sure of your conclusions regarding Galland's specific aircraft, so I am willing to defer to your depth of experience:
The film footage was taken after Gallands 57th victory which was on the 28th Nov. Spinner Cap, engine upgrade, new camo was done sometime between 28th Nov and 58th victory on 5th Dec. as new camo and repainted rudder shows 57 victories then 58.
I'm happy to take that as the basis for my scheme for the aircraft, unless someone disagrees vehemently. So, Nov 1940, 56/57 victory bars. As the profile below, with the extra bars?
Profile 1
Picture 2 is from Najco, from his own Thread. This looks to me like it might be the profile of the open spinner, what do you think?
The other thing I'll cover here are the Abschusse markings. Up to the point that I got the Techmod decals, all colour references I'd seen for them have been in black. But looking at the deliberate way they've been laid out by Techmod, it looks like someone there gave it serious thought, possibly from a reference.
Picture 3. Not just split randomly but 3 rows of 30, red then 34 35 in red also. I would be reluctant to use these, unless there was some other verification.
But there was something else I found that could support this.
Picture 4 is a Photoshop b/w conversion. You can see the difference in tone between black and red. Now look at this reference from Maria's post on Najco,s thread
Picture 5.(The markings are hers.) The first 37 seem to be lighter than the next 13 (see the different contrast on row 4). Row 5 seems darker. It's hard to call row 6, because of the shadow but 59/60 seem lighter again. I appreciate that this could be down to natural fading or lighting and although the pattern is different from the Techmod decals, could this have been a split colour scheme? It bears consideration.
