I've listed this under Great Britain/Other. The instructions are from Primus-Sievert UK Ltd with a factory address in Formby, UK. I've never seen these outside of the UK & I suspect they were a Primus-Sievert UK product for the home market. I also suspect this is 1970's to early 80's from the telephone number code & the fact the stove at the core of this heater is a Hipolito No:1 rather than a Svea. This also comes with the pan-ring & legs so the stove can be taken out & used as such.

The buyer, Fra, is a member here & contacted me recently & offered me a deal on it which I couldn't refuse. Thanks Fra!
