How to function test an old lantern before you buy it
If you're looking for an old Coleman lantern, you can find some really good deals out there. However, if you don't know what you're looking at, you might get one that needs so many repairs that it exceeds the cost of a new one. That's not always a deal breaker, the old lanterns are better than the new stuff they turn out. This is the way I test old lanterns to give me a good idea of the repairs they might need without taking the whole thing apart... Taking things apart at the thrift shop is generally frowned upon by store owners, lol, so this method only goes over what you can check while in the store.
