Here's my "Lamb" Petrol Stove that I've finally got round to restoring: I'm not entirely convinced the spirit can is original. I'm also missing the chain that secures the reserve cap to the carrying ring so it doesn't get lost, but this can be replaced with a key chain for a 123 or similar. The stove comes with these pieces of metal: These slot together to make a surprisingly stable pan rest: The jet pricker is original: And just to provide an idea of size, here's The "Lamb" alongside a Primus 96: In terms of date the JS&S post in the Manufacturers section says JS&S acquired Lamb in 1914 so this stove cannot predate that year. Also in this Ross/Mick Emm post it seems to indicate that this stove came in a tin/post rest version from 1924 onwards. So provisionally I'll date my stove as between 1914 and 1924 unless they continued production of The "Lamb" Petrol Stove without the tin after 1924. Note this is a different model to Kerophile's "bunsen burner" version as I notice that stove has a safety pressure release, and a different shape carrying ring. Normally I would be happy to fire up any stove that I have fettled. In this case, whilst I can see no reason why it shouldn't work OK, given that it's petrol/white gas fueled, has no control valve, has no safety pressure release, and relies on lung power to extinguish the flame I don't think I want to risk a potential flare up and thereby lose an interesting, pretty, and relatively rare little stove.
