My uncle gave me this years ago and it's stayed in my attic for years. I will attempt to restore it someday. I used to have the top plate for sitting a pot on top of, but it's gone missing somewhere.
Hi David - welcome to CCS. A great family heirloom! I have split this from the Primus 8 post in the Stove Reference Gallery. What you appear to have there is the Optimus Auto No:8 - the perforated spiritcup was a feature of that model. They were supposed to self-start without pumping. Not a common model.
