#1 Son didn't like the "Flipper feet" so I've put together a 3D foot. This is the last part that needs scanning and converting to vector format after which I'll be adding colour to the parts.  (#1 Son approves) 

I've changed the head to make him less manic looking. Photographs all seem to show Isambard Kingdom Brunel as a suave looking fellow.

And here he is, all but the right foot.

I've made the head pose-able. It moves side to side and up and down.

Colour next, then a display box.
