The top of the hinge has the lego logos on the studs, but the bottom half not
yet, I assume a very early prototype fase.

Which, if they are genuinely from LEGO would lend credence to protype. Industrial
3d printing has been around for almost half a century now.

That wouldn't explain the plastic injection points on the studs.
Also, the parts are much too glossy for additive manufacturing. Those parts were
molded.

Unless someone really did their homework.
OP, where were these sourced from? Did you find these while parting out?

So, would it be the mould that was quickly prototyped / left unfinished (roughly
milled)?

Yes. It takes a lot more money to finish a mold with precision. This definitely
looks like a prototype mold.

Great find!
The colors compare to LEGOland colors used in the 70s and 80s before they became
mainstream.
It looks like the molds were prototypes, with the rough surface.
Any markings on them, mold number etc?
More pictures please!

I would have guessed them to be younger, this type of hinge wasn't used in
the 80s yet - with a quick look in the catalogue I see them appearing from 1999
on. Earlier they used these connections for hinges:
* | | 4276b Hinge Plate 1 x 2 with 2 Fingers on End - Hollow Studs
Parts: Hinge |

For that kind of hinge-movement, there was:
and then the couple (frictionless):
And now, there’s also (frictionless or not, depending on the pin you use):

I was more thinking of these being made instead of the older type hinges.
Maybe they did not like the design and stored it for the time being.
Or my time line because of the colors is of….

A few years ago I have acquired the collection of Daniel Krentz, designer from
1970/1996
In his collection were lots of gems like these, prototype parts, parts with only
TF or FF in it, and some parts even with partnumber that were never released!
So I know for sure it is genuine Lego, I always wonder how the designers in those
days would go into the factory and try out new things 🤗

If only it was Pat. Pend.... 
The one on the left is a 3d printed prototype, indicating where the logo/text
and the injection point will be placed on the real part. I think that they could
not print text that small back then.

I agree they look weird, but if they are 3D printed, why have a molding pip and
why the rough prototype surface?
Looks more like a prototype mold quickly made to work for prototype part making.

If you already knew this, why start a forumpost with ‘possible prototypes????’.
And, although I believe they can well be prototypes, if a 3D printer prints a
part from a real example with a injection mark, wouldn’t it print the injection
mark too?
