I'm looking from afar: It seems to me, the MOBIDIC model in discussion, has some value as a historical object to various collectors. So such models will command a price of hundreds of dollars. That's the apparent opinion of the recent eBay seller of such a historic model. However, for purposes of display at the VCFed Museum at Infoage, any constructed physical model of some version of the MOBIDIC will I presume be acceptable. It's a matter of desired size and quality. There's already a model on display; another seems to be desired. I do not construct models, but the MOBIDIC models I've seen here and there, seem to be of simple construction, commercial applied labels stock, etc. It also seems to me, there's a model railroad organization at Infoage. Their members build models of industrial settings at many scales; they know other builders of such models. Their models, by my eye, look as good or better than the MOBIDIC models I've seen. Therefore: why doesn't VCFed approach the InfoAge model railroad organization, and inquire about construction of a model, provide desired size, and show them images of the various models and images of actual MOBDIC computers? If the answer is "we don't wanna spend money", then the response might be "someone may donate the funds" in the usual ways. You won't know the price if you don't ask. Beyond this, "I have no horse in this race", these are simply my observations as noted, for consideration by those interested. Herb Johnson -- Herbert R.
