The SM 67 mask remained in production at least until the mid-1970s. Here it is in 1974:
Italian: "SM. 1) Gomma nera di speciale morbidezza ed elasticita. Ventosa interna per una completa tenuta. Bloccaggio a pressione del cinghiolo. Sede nasale atta ad una facile e immediata compensazione. Ghiera in acciaio inossidabile. Cristallo temperato. Ampio e libero campo visivo. Ridotto volume interno. Imballo e spedizione: scatole da 20 pezzi."

Stainless steel band. Tempered glass. Wide and free field of vision. Reduced internal volume. Packaging and shipping: boxes of 20 pieces."
