Here is my example of this lamp. It appears to be in unfired condition as there is no soot in the hood and the enamel isn't cracked and lifting on the top. I have based my dating on the fact that it seems to be the same as Neil's example. Unfortunately it also appears that I have managed to get the only example that has at some point been dropped on it's end and as a result the wood blocks that hold the tank in place in the box have put a nice dent in each side of the tank. Oh well... Otherwise I hope you like it.
