This is an Optimus 700F that I rescued from a scrap bin. The pictures show it after an initial clean and a straighten, the reflector was rather bent and split. The top of the burner was missing so I borrowed a burner inner and out cap from my Optimus 1S to test the heater. Doesn't hold pressure well so I have ordered a set of seals from Fettlebox. Does anyone know where I can get the correct burner top as shown on the other Optimus heaters in the gallery?
