Got back to Canada a few days ago; did manage to see the Q1 in York, and did get to the Harrogate show for a few hours on the Saturday. (Saw 4 of the A4s during my trip, and a 5th, have been through it here when it was in Canada – none nearly as interesting as the Q1, IMHO) 
Did not see any Q1s on the stands at Harrogate. Looked at the Polly stand, but did not talk to anyone – they were busy enough with paying customers.
Did I miss one? The exhibition was very busy when I went, so possibly I did miss something on one of the club stands.
Working through the CNCing aspects of my model engineering – have re-drawn the wheels in 2D CAD; also some parts that will be water jet cut.
When current workshop projects come to completion, the Q1 may pop up onto the top of the list – have boiler materiel to make 2 boilers, so possibly 2 Q1s will be made in my workshop? (It'll be documented on http://cnc-for-model-engineers.blogspot.com, along with other aspects of my CNC education)
