I would like to chime in on this thread. First, I have the impression from the comments that there is an assumption that errors or flaws noted in the model would not be corrected. I hope that impression is incorrect. As you may be aware, I have personal experience with Martin of Travel by Train and what I noticed was that he appreciated any information that I could give him, in particular when I backed that up with photographs and source material. My impression was he was VERY eager to get accurate information and put that into his model to make as true as possible to the prototype. While there were some things he couldn't correct like the font, I tried very hard to get it for him, and when I couldn't, I let him know that it was a close as could be with what he had to work with.
Martin was the first of 3 different developers I have worked with, and it is my impression that the amount of research time required to evidence particular features and characteristics of a model can significantly eat in the time to actually build the model. And I know - I put in 20 hours of research for Martin finding images and good logos for him.
I would say that this developer is committed to making the best product he can and appreciates any help that we can give him. So don't be shy, reach out with issues and help him out by sending him images and evidence of what you have found. Where I am coming from is that we each can have a relationship with the developer (if they are open to it) and help make a better product for all of us.
Yes, I am biased - but that shouldn't diminish my commentary!
