peck: That Peterson cap does keep the burn slow. The clip-on, screen type, in my experience, can, at times, cause too hot a burn. These I shield with my hand, the Pete seems to do okay just hanging from my jaw.
Peterson quit making them about a year ago. I contacted them in October of 2017 about ordering one, they responded with the fact that they no longer make them. They said that the company that made the lids for them has stopped making them.even new they are not common, I read somewhere they are special order..
