I bought this stove on French eBay and clearly the seller had done a great cosmetic job but the stove had seized up. The control valve was difficult to turn even once. I disassembled the stove and packed the valve with graphite. This freed the control valve which now turned easily through several revolutions. However the cleaning needle was failing to drop meaning the jet was blocked so I removed the jet, needle and the spring and cleaned the needle housing. I also stretched the spring a little to give a bit more push on the needle to move it down. This did the trick. The stove was bone dry so the wick took a while to soak but eventually she came back to life. For those unfamiliar with the stove I've included a shot next to my 8R for size comparison.
