You stated "Despite being painted in a late war scheme, Yellow 5 had an older style spinner. No spiral or white segment, just overall blackgreen RLM71. I used the Testor's 71 which seemed a bit too light, so I added a few drops of black to the mix. Once it was dry, I used a very fine section of stretched sprue to add some silver scratches to the blades and the spinner." Can you describe how you used the Sprue and what paint you used? Thanks
