When I started work on the Skytrex ruined barn casting, someone suggested it had been mastered by David Wright of Dovedale models. Having chatted with him at Derby, I can confirm this is the case.
Inspired by this model:
a request was made for a version suitable for casting in resin. The master was madein foamboard and DAS. A mould was taken from this and then lots of resin versions produced.
A tenner for such artistry sounds like a good deal to me.
