Here is a very nice working Optimus 8R backing packing, camping, hiking or road trips cooking stove, very lightweight and compact.  Everything is in very good working condition, no dents or damage of any kind.  Fuel needs to be white gasoline such as Coleman fuel.  Stove measures 5" X 3" with a dry weight of 1 lb. 8.7 oz and comes with the fuel adjusting key, also used as a field repair tool.  The orifice cleaning is automatic when first fully opened and turned back to high position before lighting.
