Saw that programme too, They were nicely painted from what I saw. I thought I recognised the a firelock soldier from the back of the firelocks box. (The one singularly pictured if people know what I'm on about.)
The programme itself was a bit ropey though and I thought could have been condensed into about half an hour really. It felt like the investigators were speaking scripted dialogue too. Some very questionable suppositions too.
Just checked that link, some nice minis on there but no Warlord ECWs- have the beeb nabbed them?
