Thanks for the replies. Yeah, the license lapse might be the reason, makes sense.
For Ursus, the print quality seemed fine to me. I'll photo later and post up here - will be unwashed and unpainted.
As I recall, they were available in several sizes (which any competent 3D printing company should be able to offer - just be aware of original design size as smaller sizes from larger originals can get increasingly fragile with some portions of the prints). The 15 mm ones I have seem quite robust.
And later...photos...

Nice sculpt for my purposes.

The whole lot.

And a size comparison, a Splintered Light Robin Hood figure - larger 15 mm, shows the gorillas to be a bit small, probably better for 10 mm but will work fine for my purposes. Now if I could only find some good chimpanzees to add to my collection!
Hope the photos give you what you need. I also ordered from same source some sheets of corrugated roofing I will use to add some character to some pulp buildings I have in process and they will be fine. Do keep in mind I am not a contest quality modeler, just someone who creates things for fun - it is the overall experience I am after, not one beautifully painted figure/building at a time. I say this so you know my standard of approval might be less than yours.
