Hello, Here is an Optimus No. 48 which I recently found in our garage. It must have been there at least thirty years. It is missing one trivet leg and the trivet itself is rusty. I washed the exterior with dishwashing liquid and hot water and had a vague attempt at polishing an area around the engraved name and the underside with Brasso. I haven't attempted more than that yet, as you can see. I'd love to know how to restore this. I think I'd prefer it not to be restored to a shiny condition as it wouldn't stay like that for long, since I intend to use it. To be honest I've never seen it working and I wouldn't even know how to light it or what fuel to use (kerosene?). It can be pumped up and seems to hold pressure just fine. Any advice greatly appreciated. Thank you.
