I have an Optimus 182 range, think I've become a "rangie"
It's like the one in the 1952 brochure on this wonderful site, with the cream enamel. It has a nifty level indicator on the top of each tank. It's missing the "spirit channels" shown on the brochure. I suppose they were loose pipes that ran from the top surface of the range to each spirit cup (I wonder if flames ever shot out of them?). There's just the two holes in the front of the top surface of the range as shown in the picture. No worries though it's not too hard to fill the cups with my new plastic squeeze bottle. Interestingly enough the outer burner caps are steel. I thought these were always brass. They are prime candidates for my electrolytic rust removal bath.
I have fired up the left hand burner, all OK, level indicator working nicely. The right hand side may need a little attention.
If anyone would like to ask any questions, please fire away.
Dave.
