Cheers. Yep, all the buildings are built around plywood shells. Colin is a cabinet maker by trade (he used to be a commercial baseboard and model display case builder too) and tends to use timber for building …..well pretty much everything he can!!. If memory serves he uses the same superglues in modelling that he did for cabinet work. As for the etched details the building includes a pair of very unusual oval windows with brick surrounds. So, like the Hull & Barnsley signs, none are commercially available so we had them created thanks to the etching talents of one of our number.
