Based on some preliminary research, the patent term in Italy appears to have been 20-25 years, indicating that the patent expired sometime during 1954-1959. Somebody with a better understanding of Italian and patent terminology may be able to confirm and narrow this down.
Do Mavic rims carry the same Longhi designation?
