In fact, the ancestry of Sheaffer is seriously under discussion; in fact, there are previous versions of this loading system, a Swedish Johansson patent from 1898 and an American Barnes patent (nº US-726495) from 1903, the presence of which has allowed other companies, such as Waterman, to use variants of the same system. However, the success of the system and its enormous diffusion can be attributed to the massive investments of Sheaffer.
