To find the date of manufacture of a Coleman lantern, check for a date code stamped on the bottom or side of the lantern. This code typically consists of a series of letters and numbers that indicate the year and month of production. You can also refer to Coleman’s official website or collector resources for specific decoding information based on the model. If the lantern has a model number, researching that online can also provide insights into its production date.
