A clone of the Optimus 8R. Of note: Lid folds back flat to use larger pots. Lid can be removed easily to be used as a pot like the Optimus 99. Lid interior is coated / painted - so not sure I would want to use it as a pot though. Windscreen around the pot supports. Tank size compares well with my Optimus 99 and the tank cap interchanged without problem with my Optimus 99 tank cap. Other than the tank and burner assembly - all parts are steel.
