JCWohlschlag,

Now that's exactly the kind of info I've been looking for. Will have a go, when I get back home.

The only reason I assume it was a photon III, is that all the latest III's have just one push button switch. I thought that was the evolution of the photons. I have one of the early slide switch's on the photon I, and I have one of the latest gen which just has the one push button plate/pad.

Thanks everyone that's made I contribution to this post. I'll be back with comments if it all goes pear shaped.
