Very cool for what it is! You decide, check out the pictures. Atlas "The Detonator" Blasting Plunger! #1 In explosives! I don't know alot about when this was made or by who or what company. I ran into a few and bought them some time back. This is a replica of a early blasting box. Handle goes up and down, has brass screw connectors, (this does not have the ornate ends on the handle that show up in the picture). Says Star Mine Burke, Idaho. Has a push button kill switch and wire leads. All the lettering was wood burned. This is a non working display piece. Great for home or office. Measures 5 1/2"x5"x8" tall. Sold as is!
