Wanted: concept airliner models (scale not important)

[Mark22]

I am looking for models of civil aircraft that were used as concept or for presentation / demonstration purposes. The pictures below are examples of what I mean, the JAL 7E7 is mine so it's the only one I am not interested in. Scale and livery is not so important. Maximum size is about 30cm, which is equal to a 1/200 MD-11. Must be in good condition and preferably with stand. Budget highly depends on the model. Not sure if they exist in the size I'm looking for, but the only way to find out is by asking .

Trading with a variety of 1/400 models and pickup at the Amsterdam Fair next week is possible.

I know that GJ and maybe DW made concept 787s, like the ANA, saw one of eBay not too long ago

Bluebox made lots of them but I already got one.
