Hello to all! Well, I dug a hole for myself... I have a Primus 1020 circa 1935. This is a beautiful lantern and one of my favorites. The NRV finally crapped out on it and I am having a rough time trying to remove it. I have the "special" tool for removing the NRV but I have been trying for so long I've rounded the sides of the NRV and now I can't get the tool to grip it. I've tried penetrating oil, filling the tank with boiling water for 10 minutes, etc and I still can't get the damn thing to break free. Pleaseeeee help me!!!!!!
