On this topic: I'm well aware multiple audio releases for this and, a seemingly never produced series "Ohige no Namazun" exist. That said, I'm also not entirely convinced the studio doesn't just have the original film lying around. It's an early sunrise production, and while some Japanese studios have been spotty on taking care of film or will give the runaround on if they have certain things or not, generally speaking, most Japanese studios hold onto these sorts of things. Until they release it, it's still "lost" or presumed so, but I'm willing to bet as more things like Guzura, or Kaba Totto from studios like Tatsunoko come out, other studios will begin digitizing their library as well.
