Your jacket is a 100% authentic, modern-era Schott jacket designed with a heritage/retro aesthetic, rather than a true vintage garment surviving from the 1960s–1980s.
The biggest advantages of these contemporary models are that they feature a more comfortable, slim-fit silhouette optimized for everyday modern wear, and they generally utilize softer, more supple leathers (like sheepskin or cowhide) that do not require the grueling, years-long break-in period of stiff vintage steerhide.
