Thank you guys for the nice comments! :drinks
Until now I've been using Brett Gooden's Project Natter as a reference book but I ran into a book in German in a local bookshop the other day, which I wasn't long in buying. Got it at a bargain price too!
Both books have a nice contemporary document with the markings and stencils of the operational Natter.
It clearly says the nose is RLM 23 Red, which I'm all for! Let's bring some color to this bird.
The red nose makes sense too. After all the C-Stoff was an alcohol-based mixture.
There are no stencils included on the kit's decal sheet so I ordered them from my favorite tailor-made decal provider. He's good but a bit slow so in the meantime I turned my attention to the launcher and base.
The pole has hooked spikes for the maintenance crew to climb but I didn't like the kit's over-sized plastic ones so i removed them and replaced them with new ones made from copper wire.
I also added a piece to the bottom of the pole to insert into the base (a piece cut from a pen of the right size).
Choosing the right shape for the display base bugged me for a while. The launcher was erected on a slab of concrete that was round. Choosing a round shape for the display base (round on round) would have been ugly. Square or rectangular were equally out of the question. Using a random shape works, though. (My wife said it's shaped like a :love...

)
I used cork sheet to make the substrate for the concrete slab.
The German book came in handy here. It explains that although the concrete slabs are 4m in reality, contemporary documents show they were supposed to be 8m in diameter. I decided to go with the size shown in the document which fits the length of the pole's swing arm.
More to come...
