This is a Canadian Black Diamond Brand Shaft Sinker's/Miners Hat. This style was worn in Lake Superior Region Iron & Copper Mines ca. 1880-1910. Marked "7002 L". I believe the velcro neck ties have been added later. The hat is in very good condition, all black rubber with cotton interior. As I am not an expert on mining hats, info has been researched. Check out: helmetsandhats - mining artifacts, and the Canadian Science & Technology Museum Corporation, Ontario, Canada. Perfect for the collector or a Museum piece!
Feel free to ask for more info or photos as we have a strict no return policy. Thank you. Have a great day!
