This skin was based on USAF roundels from 1947, but there is also an RAF version.
If you find any error or anything that looks abnormal, let me know. I'll fix them ASAP.
Important note, this skin was based on a Spitfire Mk VIII model by TAMIYA, check the link below for more info.
Also special thanks to Razor for helping me out! You're the man!
