I was recently passed a link to a YouTube video by a BBBQS member showing a smoke salmon slicing demonstrations at the Forman salmon smokery in London. Darren Matson (the man who has taught many top chefs the correct way to carve salmon and who is in the Guinness book of Records for Smoked Salmon slicing) gives the demonstrations and you also get a tour of the smokery.
You may be interested in the videos - they appear to have been filmed on a mobile phone so the audio quality is not great.
It should take you on to part two automatically - but if it does not the link is here
The last demonstration and smokery tour this year is in a couple of weeks (which I have booked myself on to) but they should start again next year in April if anyone is interested. Information can be found here.
