I recently came into posession of an original , unfinished, Alethiometer prop from the 2007 Chris Weitz film The Golden Compass, based on the 1995 novel by Philip PUllman. As it's unfinished this isn't a screen-used piece but it is production-made with provenance. The original Alethiometer props, a fully working-dial version and several closed 'stunt' versions were made in cast and machined brass from high-resolution 3D printed master patterns. It was pretty early to be using this technology to produce casting patterns but no expense was spared on the production design of this movie and the results were superb.
What I have then is one of the original patterns. It was sold as being one piece with all the detail of the finished brass parts except the three 'watch winders' on the outside. I studied the piece very carefully when I got it, several times, and have just realised there is a slight parting-gap next to the hinge detail which has allowed me to get a soft edge in there and prise it apart into a full shell with a smooth finished interior! I'm really pleased as the original description didn't mention it was in two parts and the photos showed only a solid piece.
In an ideal world I would like to have moulds made from this piece and cast up some new Alethiometer cases but the surface detail is so fine I'm afraid it would all disappear during the casting process. In the meantime I'm just glad to have an original Alethiometer...
