John Date Diving Helmet
Late 19th century diving helmet by John Date, the only helmet manufacturer in Canada. Based in Montreal in 1853 as a brass foundry, he started to manufacture diving helmets. As early as 1876 his diving equipment won awards in the United States. His earliest helmets had a wide breastplate with a non-recessed neck ring. Little is known of this early manufacturer but the quality of their workmanship was of the highest standard.
