Hi mate, I have the same lantern as you and I think I have purchased a very similar mantle (500 cp). After realizing about the size I thought it was the wrong mantle for this lantern but looking at your video I see that after it shrinks, it doesn't seem bad actually. Is it safe to use these 500 cp mantles on your Coleman 286A or what other things have you experienced with them that are worth mentioning. Probably you have explained it already in your video but sadly I can't understand. Thanks in advance.
