Archaeopteryx 1:1 retro model

[DinoToyForum]

I've raised this before a long time ago, but can't for the life of me find the discussion, so I'm setting up a new thread. There are two identical 1:1 Archaeopteryx models in the Nottingham Natural History Museum.



I don't know when the museum bought them, and there are no markings on them, but the style looks like they could be from the 1960s.

They are made of plaster and painted. The claws seem to be reused real bird claws.

I seem to remember, when I shared these before, someone was aware of another one in a different museum, and may have had some background info on their origin. Was it @Halichoeres? If not, does anyone know anything about this model or seen any others?
