This is an old cast iron camping stove. This stove is all original and in excellent condition. The manifold has been fitted with modern fittings and is ready for use. This stove was in working condition eight years ago, the last time it was used. These are very simple in their construction. It should operate just fine if used again. I cant come right out and say that it runs fine because I have no way of testing it, however it has been in the family for ages and I know its history.
