I know that I said there wasn’t going to be any more shots in the polygraph series, but I couldn’t resist including this one. I decided to take one last look through the various ones I’d taken, and thought that the composition (if nothing else) warranted this one’s inclusion.

That said, as I look back through my previous entries, I can see that these images haven’t been overly popular (if the number of comments are anything to go by) so I will refrain from posting any more of them ;-)

And this is marginally related: I had an email a few days ago from someone interested in buying the polygraph. He’d done a google search for ‘Grass Model 7B polygraph’ and came across the first image in this series. Unfortunately, it isn’t mine to sell, as I imagine – given its complexity – that it’s worth a reasonable amount of money ;-)
