This might interest someone out there. Bonhams has a sale on Wednesday 14th November 2012 at Harrogate.
There's a 1945 military field kitchen on offer with an estimate of £1,000 - 1,500 (€1,200 - 1,900). Don't know anything about these things, but if you've already got a half track, a bren gun carrier, a howitzer, a Sherman tank, a Lancaster bomber and a Mulberry Harbour, you just gotta have a mobile barbecue.
