I'm not sure that Mr Spoerer is still in the business of selling stuff like that. Anyhow, Mr Dodger lives in the USA, and would be far more likely to get one from Jim at Southern Steam Trains. Cheaper, for sure, not having to pay the UK price including 20% taxes and international shipping, right?
BTW, in the USA it is called simply 'alcohol firing'.
