Coleman 400A with box and instructions, it looks as though it has not been used, there is a mark on burner bowel and a black mark on the generator but no smell of fuel in the tank.
@Moist nugget I got this around 6 months ago at a nice price, that said generators are near impossible to come by, so it wont be getting used. Keep looking you will find one in the end.
That is a real nice stove! I have the exact same one. Except it is in a little less new state But it has a blocked generator, I have to see if I can free it up. I also have it's bigger cousin, the 508a which also has the same kind of generator. That one works great, fortunately. But it will only see Coleman fuel/naphtha for sure!
