Richie this has been one of the most game changing pieces of modelling I have seen in a long time. The use of plasticard as opposed to brass is completely new to me as are the windows. In practice it works, and it works really well. You have changed my perception of what can be achieved with what you have been doing in the last year regarding coaches, I could see a package being delivered and on opening the package seeing the contents like I would see a well thought out kit which would be a pleasure to work with. I also think it will make this area pf the hobby more accessible to modellers who might be a little nervous working with other materials,.Which is a very clever idea on your part, and I am sure very welcome to the hobby.
Great work,
Rich,
