Thanks again everyone for your comments, I think I will need ongoing encouragement as my time for building this model is running out! Deadline is Thurs 7 June which is not far off....
As well as unnecessary rib detail on the axle wing, Revell included exaggerated spoke detail on the wheels. Again this was scraped, sanded and polished off before I hit the wheels with paint - MRP's Richthofen's Red to be precise. This is the first time I've used MRP paint and I'm very impressed. The lacquer formula is something I'm familiar with and like (apart from the smell!), as I normally use Tamiya and Gunze acrylics thinned with lacquer thinner - I find this gives a good strong base for subsequent weathering etc.
You'll see I've also painted the seat red - according to the instructions in Cutting Edge's 'Baron's Tripes' 1/32 decal sheet, the seat in the plane in question was covered in red-doped fabric. I don't know how accurate this is, but it does look good! And the seat is a replacement - it's Aviattic's lovely 1/32 Fokker seat which while slightly underscale is not obviously so, and is far, far superior to the quite nasty kit offering (of which I unfortunately don't have a photo to use as comparison).
And if I'm taking some trouble over the seat, then I also need the canvas screen behind the seat that is not included in the kit. I've made this up from scrap Evergreen card and rod and - while it looks pretty rough here - it painted up really well as you can see in the following photo of the cockpit - more on this in my next update.
cheers Brad
