Just for ease of searching for solutions later. The model is Optimus 8R. A newer version of the Optimus 8. Like a Svea 123R is a newer version of the Svea 123.
Gotta love an OP. 00. From the design on the tin, I would say yours dates from about 1955 or so. Makes it about 70 years old. Plenty of life in the old stove yet.
Cheers Dean it worked out the box need to get a flame spreader for it next. I did ponder on making one but think I would like nice authentic one
