This is a close cousin of the Flounder lamp. Designed for much the same purpose but with a strap to hang on a nail or hook. This is the only example of the model I know of with collectors. Fitted with a two air tube burner. This one sold by A. W. Thacker in Florida USA. As with all these small lanterns an export model not sold in the UK. ::Neil::
Juan. No I am getting to that one. The flounder lamp is model X458 which I am about to post. Took me a few hours to find it. ::Neil::
