Who built Celia Sheen's theremin?

Celia Sheen and her performance on the Midsummer Murder soundtrack has been introducing a lot of folks to the theremin.
(It's a great melody for the theremin too!)

Does anyone know who built her theremin? Very different looking and nice tone.
Here's a link to someone's screen snag (http://1.bp.blogspot.com/_E0YYe6c0a0g/TEDTHMbGMsI/AAAAAAAAAWg/mKevP7Ml_Ek/s1600/Theremin.jpg) that shows it well, it's from her video of playing the TV theme.

I wish she had a web site, she's been playing on several important recordings and TV shows recently and deserves to be better known, I think. Maybe she is, apparently she's a professional violinist and maybe she's studied with Lydia? I'd like to know more about her, please add on here if you know about her or that long rod theremin she plays.

Here's the, now couple years old, video if you haven't seen it yet.

This theremin has been built by the (now retired) british engineer Anthony Henk. He made only a few of these theremins. Then (after what I've been told) he saw that building theremins would never be a real business and he stopped frustrated and retired. It seems that he gave all schematics and plans to someone else, but I couldn't (yet) find out who that was.

Anthony Henk built also the theremin on which Lydia played from around 1996 until her husband started producing the tVox tour. This Henk theremin has separate housings for the pitch and the volume part and was mounted on a stand in "U"-form. You can see and hear it on youtube with Lydia performing "Clair de lune" and "Vilia's song". It has also been used for the recording of both her "classical" CDs.

Unfortunately this wonderful instrument which was the most linear Lydia ever owned (her own words) is now defective and remained in Moscow. But there are actually rumors that it will be brought to a certain French "thérémingénieur" later this year and that he will analyze and try to fix it.

Funny I think of this and there is a recent post. I was thinking seriously of building my Keppinger Mark 2 in a similar configuration. I like the minimalist design.

Philip, you may also perhaps consider a cabinet as the Italian theremin designer Mattia Pegna uses: http://www.pegna-instruments.com/
