The outfit selling that Lancaster model have picked up the distribution rights to a pretty big collection of CGI models, and quite a few look to be very similar to commercial plastic kits. You can see it in some parts being a bit out of proportion, such as the thickness of the framing of a cockpit canopy or gun turret, and a lot of the buildings are straight out of model railway catalogues.

I don't think the Lancaster is one of those models.

But (going by YouTube videos) any film-maker has to compete with computer games these days.
