I'm picking up this stove in a couple days, I believe it's an Alpiner Matterhorn which I think is the equivalent to the Fisher Papa Bear if I'm not mistaken. I have a friend that has the smaller Alpiner and he has a door gasket on it. I also have a Grandma Bear which is designed to not use the door gasket. Does anyone know if the Alpiner requires a gasket? There is still a shortage of information about the Alpiners so for now I am looking at it like its a Papa. I also have an Englander 30 as my primary stove and the Grandma was a project I found for free that I found to be warped and had cracks, I ended up fixing the cracks and using it for a while and came to the conclusion that it needed a door gasket and hinge pins to function properly so I told a co worker he could have it but I liked the idea of having a backup stove incase the englanders glass broke or something catastrophic like that happened hance the Apiner project. Any tips on these things would be appreciated.
