A good exhibition, but not a great exhibition.
Most of the models were train-based, very few clocks, little in the way of tooling, quite a few Stirling engines, including one outside pumping water, a la Adam Hart-Davis.
Trains? The 10 1/4 inch gauge monsters are worth seeing!
Lots of traction engines and steam rollers chugging away outside.
Spoke to our friend Mr.Jeffrey and hovered around the stand for a bit, listening in. He didn't introduce himself so I didn't reciprocate, but if he's the short-arse who might do well to use Grecian 2000, then we've definitely met!
Following on from previous discussions, the Division Master is about as complicated as a pocket calculator selling for £20, with the exception of the stepper driver stages, so add another £30 for these. A 100% mark-up would give a selling price of £100, considering there's no advertising costs (done in this NG) and no development costs (a private hobby interest for which a company was only later floated.)
PS. Almost forgot 'cos of no interest to me - there was a huge range of model boats.
