Henckels restarted Friodur production several years ago. Actually I'm not sure they ever stopped, though they don't make the big 7/8 and 8/8 razors anymore. Obviously they dumped their old blanks in those sizes, but I'm not sure that they actually stopped production altogether. I've got one of their new Friodurs in 6/8, with the classic white Twins scales, and it shaves comparably to my vintage Friodurs. Nordstroms carried them as recently as 2005, though I got mine from KnifeCenter for quite a bit less.
