I think if you getto the stage where you need to employ other people you are doing very, very well! I'd say that the majority of small businesses within the model railway world are subsidised in some way, though mostly through someone giving their time for nothing and we are blessed that so many people are willing to do so. I think most of the products and ranges that are outside of the RTR world would simply not exist if they were produced on a purely comercial basis. My range of products would not exist if I expected a return on my time to draw up the artwork as I've never paid me a penny for that and nor did I ever expect to. Given that I'm hardly likely to produce things that I don't want personally. That would be more like philanthropy than business.
Being able to work partly within the field of their hooby is wonderful but I it is harder at times to deal with some of the b**l s**t that you have to cope with, especially when it comes to people whinging about prices when things are subsidised in some way already...
In terms of how all this relates to Coopercraft I think the only really viable future for the injection moulded items in the range is for someone to approach Coppercraft and take them on, assuming the moulds are good. Recreating the moulds from scratch is a non starter unless someone is prepared to invest an decent amount of money which they are unlikely to ever see a return on. 3D printing is fine except that it is still very much a prototyping technology not a production one which is why Bill Bedford gets his cast in resin. They're expensive to begin with and if you expect a return on your time to produce the artwork for it then things are going to start to get pretty pricy which obviously limits the market...
