Amazon's "Truth Seekers" Electroplasmic Spectrometer Help

[PropsToHistory]

So, Nick Frost and Simon Peggs recent outing on Amazon has at least a couple of really fun props. one of them is the "Electroplasmic Spectrometer" which Nick Frost's character uses

Spoiler

to detect ghosts

<--Spoiler

The main component is a Morgan Series 900 Mini Monitor. The one in the show is a Thermo model, but structurally they seem to be the same. graphic are slightly different as well. This is the one I have already.

The issue is the "wand " part of it. I have no idea what its made from. I believe the base of it is the detector from the Series 900, the rest...help?
I did my best with the few screeen grabs that i could get.

Lucky find on ebay. It was sold as parts. When i got it the battery wire needed soldering.

Works now
