Thanks again for looking in guys and for the kind words and well spotted John, they are raised panel lines on what is an old Revell-Monogram kit, this one was released in 1985 when raised panel lines were the new thing on aircraft kits. It also shows that I was completely lazy and decided to leave them as is, rather than do that hated job of re-scribing.
Anyway folks, she is done and here is a sneak preview. All I have to do now is take some comp pics once I find a decent light location in our new home.
