I wonder if you want to exchange photos of Shell, BP, Esso, Caltex, Chevron tankers from 1920s up to date. I have a large photo collection of tankers from 1920s up to ULCC:s worldwide. I was sailing as Chief Steward for nearly 25 years under the swedish and other flags in worldwide trade. Brgds Jorgen Lonn jorgen.tankers@gmail.com
