They look good, glad you didn't add spillages from the the top of the tank, I watch TEA fuel tanks go past North Stafford Junction on their way to & from Kingsbury never seen fuel spill from the top of these tanks! only on the side of the tanks are rubbed clean by bushes!! pity I can't share a photo on comments.
Nice to hear your voice Matthew. That might inspire me to do mine they’ve been the box for 5 years 😮ps just found them they are the ICI tankers from a Hornby mag subscription 😅Fred
