I had this in my files for a long while, but have never uploaded any of my FW19 skins until today.
I do not allow any aspects of my liveries to be taken and used in other works without permission. I also do not permit the redistribution of these liveries on other sites. (If you want to use something: Just ask!!)
FYI: This is not 100% accurate. It was never made for release, so there are some problems. However, I think someone could get some enjoyment from this.
