I've had this lidless model, two burner stove a few years. Used a Coleman oven to fix a game hen and sweet potato a few years ago for Thanksgiving while camping. Worked great, except I didn't realize I had the main burner up too high for a little bit of time as it scorched the nice decal on the front. Bummer. I've used the oven to make brownies and cookies also. Had it out last week camping, it seemed to have a minor leak out of the valve, replaced it today, now no leak. Runs great as you can see. Has the old burners, simmers very well. Duane
Forgot to mention, the photo after the burner on high has the scorch plate in it, under the phamplet. Wish I knew what it was before I used the oven. Duane
My 417B is my fav, has those same cast burners w rings. Looks like your has one more ring than my 417.
