The (non-operational) Automatic Crispin was displayed at ExpoEm in 2016.

The manual version, in the form of Crispin himself, was also present for the occasion.

I have some photographs somewhere...

You could contact the Shoeburyness Club exhibition manager (Roy Ginn) and offer your layout for this year's show.

Looks like it would fit in well there, and be of (relatively) local interest too. Your story of 'idea one year, exhibiting the next' might be deemed a useful publicity feature for them.

There are contact links on their website.

I was there exhibiting myself at the 2014 show, on the MERG stand.

I can vouch for the adverse weather conditions, especially on the Sunday afternoon during pack-up.

Afraid I can't claim the accolades for this PCB version. Looks more like the style of Trevor Stockhill's boards.
