I remember seeing this thread years ago, must have been near the start. Mind boggling attention to detail, this was a massive project and he managed to keep it alive all along. Made pretty impressive progress too from the looks of it. Sincere condolences all around for his friends and family.
I do hope, as this is still a modeling forum, that somehow the stars align and this huge endeavor manages to get passed on to a competent and passionate modeler who will do it justice. I'm not sure how often that ever actually happens, but to think of it tossed in the bin by family who might not know what else to do with it would be a true shame.
