the fettling work is here ; http://0flo.com/index.php?posts/54245 This lamp is not exactly the same as Conny's, but exactly matches the catalogue's page I own. The burner is a 150 candles power and is reputed to burn for 15 hours with 1 liter of gasoline. This burner is the inside burner. The lamp can be fitted with an outside burner (n° 501 bis) which is more shut in order to keep the warm. It could be add a shade but I prefer the design without.
