As a long.-time serious rOtring collector, your note is interesting. Who, and where can Elton be found? Just recently a German eBay seller for many years - sadly passed away. I had a good relationship with him. I would ask him for a particular rOtring art # and he would invariably find it in his “stash”. Might take him a day or two, but he would find it. He worked at the rOtring factory in Hamburg from 1970 until 2010 when Sanford shuttered the factory campus. Today I search for the earliest production “tikky” styles from 1978 and 1979. They were branded “fineline” and the very first of their kind had silver painted branding on the barrel – not for long though, as it flaked off just by looking at it!
