Where has all Wooden RHS gone?

I've been looking around for wooden rhs (especially the shinichi (wingtip) ones) and it seems I'm coming up empty handed at each and every turn. Double-Decker doesn't have them, Lolita lola seems to not be selling them anymore. I simply don't know where to look. What has happened to all the wooden RHS? I can find foam heeled ones aplenty but I don't want those, wood I much more prefer.

Has anyone seen any?
