In 1921 Amisani registered on his name the Williamson trademark (Reg. Gen. N. 20926), to create an independent production under the name of "Società Anonima Penne a Serbatoio Williamson". A precise date for the company foundation is not known, but early 1930s are being indicated, with headquarters at 12 Via Principe Amedeo, Turin, but the registration of the trademark, and the indication given in this page of the Annuario industriale della provincia di Torino (the reliability of which, however, in the presence of several inconsistencies, is not conclusive) make 1921 more likely. In the registration of the trademark, however, there is a reference to its transfer to a "Società Anonima Penne a Serbatoio" which took place in August 1934 that constitutes a definite limit to the company's existence with this name.
