Another example of the petrol version of the John Shaw & Sons (JS&S) Governor 'Lamb'. Picked it up from Ebay. Fully expected it to go for three figures (well beyond my budget) but was pleasantly surprised when I got it for well below my fairly modest maximum bid! It was described as a 'Miniature Petrol Stove' so perhaps the big buck collectors in the far east missed it. This is 'as received' (no keeping the patina with this one). I have not cleaned it: No case and it is missing the travel cap and chain (the stove has no control valve so if transported with fuel in the tank, it could leak out of the jet. The travel cap was screwed on in place of the bell to form a seal over the jet). On receipt, I did a dunk test in hot water to check for leaks, fuelled it up, primed and lit. Burned with a green flame for the first minute or so then settled down nicely: After firing it up I gave it a proper clean and polish: This petrol stove appears to have come in three versions: School lab version: (Image courtesy of Kerophile's post Link) : - this version came with three different burners: Fishtail, roarer and bunsen (shown): Tripod version: (Image courtesy of Bom Bom Bom Bom's post Link) : Cased version: (Image courtesy of Presscall's post Link) : Discussions in the Stove Gallery date these to the 1920/30s and they pre-date the Primus 70 etc. There are two types of tank cap. Flat type and winged type (Presscall's image): There are also two handle designs. 'Circular' type and 'following tank contour' type (Kerophile's image): A 1924 advertisement shows the round handle and flat tank cap (image courtesy of Mick Emm): I would venture to suggest that the flat tank cap and round handle version is therefore the earlier version. The round handle has only a very small contact point with the tank so would be prone to knocking off. The handle contoured to the tank is much more secure. The stove had no case but it fits perfectly into an old Brit Army No7 case I had spare: A line up for size comparison: Left to right - Coleman 442, Radius 42, Brit Army No7, Svea 123, Primus 71, 'The Lamb'.
