Thanks for the info, which allowed me to find some video. This is our lucky day! I haven't yet checked to see how high the pieces go up to (20??) but here are links for the first part (with just Christine) with smaller dimensions and the 6th and 7th parts with larger dimensions. No, I don't have a URL for the index pages. You'll have to, for now anyway, alter these addresses by hand for the further parts, as I'm about to do myself.
