A great suggestion was made in another thread to have a "Birthday Lanterns Wanted" thread. Please include as much information as you feel necessary. Here is some examples of lantern requirements you might use:
Manufacture Month/Year
Make
Model
Type (White Gas/Unleaded Gasoline/Kerosene/Propane)
Color
Condition
Price Range
If you can think of any other requirements I should add, please let me know.
