I decided to build a replica of the Key to Time Tracer seen in Doctor Who.
It’s basically 12 (non-lit) buttons on a small hilt with two nested clear acrylic tubes sticking from the front and a ridged/ringed tip.
I’ve based it on this plan someone made on the Tardis Makers board that I stumbled on some time ago. It’s seems to be spot on. However since the prop is not extant and there's no publicity/close-ups of it, the only reference shots are from the DVDs. At least one original (there were at least two - one broke during filming) had a light which was occasionally used in close-ups, but I decided to forego that.
(Most) pieces/parts cut to length
