Thanks fellas.
I've resolved the conundrum of the cowling directly in front of the windscreen. It just looked wrong to me.
Everyone agrees it doesn't "fit" with the rest of the camouflage on von Werra's machine. Unfortunately it was removed from the aircraft,at the site ,not long after the landing,probably because the authorities wanted to access and disarm the two machine guns.
There is one dodgy photo with this cowling in place. Modellers and profilers have interpreted this in various ways,some even going for an RLM 02 mottle. The problem is that there were rules about camouflage and if this part came from another aircraft it would have essentially the same scheme as von Werra's. The height of the demarcations did vary and this is why it doesn't line up. After much fiddling with the image I'm convinced that the "spare" cowling is painted in RLM 71/02 with a fairly normal,hard demarcation about 6" higher than that on von Werra's aircraft and that's how I'm going to do it.
There are many more conundrums associated with von Werra and his aircraft,not least of all who actually shot him down. He claimed that he was the victim of a mid-air collision(which he certainly was not)with another Bf 109. I wonder if a certain D.R.S.Bader heard that story and appropriated it for himself later?
Isn't history,and model making,fun.
More to come.......and a model too.

Edit,dry enough for a photo. Sorry it's so bad,I'm still using my phone.
