I understand they received the green light from Rackham to produce their miniatures right after Rackham folded, but the legal situation regarding the IP has remained murky ever since, especially with the several fraudulent and ill-fated French attempts at kickstarting and other shenanigans. Gibby64's endeavour here on the LAF is a positive exception though, but they 'only' do new sculpts.
Cadwallon also provide new sculpts, but additionally, they provide a lot of the originals as well. Whether or not they're actually recasts or cast from original moulds I can't tell.
I've bought a bunch of the original Confrontation bases from them about a year or so ago. Their service is prompt and friendly. One snag was that their package had been lying unclaimed at my local post office for two weeks, as I had received no alert it had arrived. So it was shipped back. But after a brief email exchange, they resent it without hassle
Bear in mind though that this was over a year ago and they are located in Kharkiv in Ukraine. Due to ongoing Russian bombing, their situation may have changed in the meantime. I am hoping they remain ok though and I am planning to order from them again in the future. But an email beforehand to check on the status of their workshop and warehouse might be prudent...
