Cheers folks, I like the .50 cal clipper Barn Owl. Managed to find a replica maker, and can get the replicas on ebay for £7-8. Also got a bid in on a vietnam version (2 x 5.56m bullets held together with brass strips - one with the flint & wheel, one with the fuel and wick).
THe WW1/WW2 ones made with Mauser or Lee-Enfield casings are a bit expensive, Vietnam ones a fair bit cheaper - maybe knockoff but not too bad - it's for a friend who was disappointed when I told him his one wasn't really made form a bullet casing.
