The Zippo Slim model 1780 is a vintage High Polish Chrome lighter manufactured in 1976 at Zippo’s Canadian factory in Niagara Falls, Ontario. Its slim profile gives it the elegant proportions that distinguish the Slim series from the classic full-size Zippo, while the polished chrome finish provides a clean and timeless appearance. The Niagara Falls, Ontario bottom stamp identifies it as a genuine Canadian-made Zippo from the factory that produced lighters outside the United States for more than five decades. Dating from 1976, this example represents a fascinating piece of Canadian Zippo history from the height of the Niagara Falls production era. Made in Canada and fully refillable, the 1976 Zippo Slim 1780 is a distinctive vintage collectible for anyone interested in Canadian Zippo production and the history of the Niagara Falls factory.
