First let me apologise for the photos. They were taken on a handheld in poor light conditions and do not do justice to the models.
Below is my only 'monkey see' purchase of the show, a Victorian aeronef. I have plans for aeronefs and aethershps in the 40K world.
The aeronef is produced by Ironclad Miniatures who do a nice range of Victorian SF. They are also very helpful and are casting some legs for me - I feel a Chaos stealth tank coming on.
Alternative SF history is very popular at the moment, going by the exhibits. West Wind had their very successful 1949 on display.
Here is one of the 1949 mechs. It is a pretty large resin and metal model. larger than a drednought but smaller than a titan.
Finally, the art people had a small painting display of astonishingly good models.
You can see this guy's eyes inside the helmet slits.
This landspeeder by Mr Dixon fascinated me because it has metallic paint like a car. It was done by airbrushing the model bright silver then airbrushing a mixture of gloss varnish mixed with colour tint - Tamiya blue in this case. It looked great.
