Finally resurrected from an originally completely disassembled box of bits. No idea how to date this other than to say that must be of more recent manufacture than my No.11 as it doesn't have the old Russian legends on the sides and only has a simple 'Made in Sweden' on the tank bottom. Up-rise pipe for the auto-lighter is missing and the cast iron pan ring is still in 3 pieces, but at least now clean, legs back on and it works. g]
