I've worked here and there on getting these released...
The owner of the first seemed amenable to releasing it, though had some concerns about it losing it's uniqueness. However, he couldn't make time to come to a get-together where it could be dumped, and has been mostly uncontactable since. I don't know if he's trying to be unreachable so that people can't ask about it, or if he's really just busy, but this one might be a bit of a lost cause.
The owner of Pink Panther is mainly worried about the rights, which I've tried looking into but hit some walls. Hopefully I'll find the time to get back on the trail "soon"...
