These are genuine Coleman parts that fit many Lamps and Lanterns of an older vintage, if you need this you will recognize them. They are no longer in the packages. Good for many lanterns and lamps, they will replace your crusty melted blobs. Check out photos. One of them is hollowed out on the back, the others are solid. The wheel features 12 bumps on the rim, the front features an arrow below and above the word close. Makes a big difference to get rid of burnt knobs for this shiny new one. Eight available. These do not come with screws so hang onto your old one.
