More then likely nobody would use a console version of any of these Philco models to make a counterfeit baby grand set, but that would be the usual path to take since the console versions of most models tend to be less collectable then the table versions.
I don't know if $3000 is the going rate for a "Walton" but rightly or wrongly they do regularly sell for four figures, the console models using the same chassis do not. I was just using that as an example of where there would be a financial incentive to create a counterfeit set with a reproduction cabinet, or to transplant a AC chassis into a battery or a 6 volt model, such incentives don't really exist with Philco Baby Grand models.
Another example would be the Philco model 511, most were Spanish Brown, but there were also hand painted versions numbered model 512 through 515. So repaint a Spanish Brown cabinet in one of the rarer schemes and you could more then double your money, not in Walton territory but still. Lets not even get into the Catalin sets with repaired cabinets being sold as nice originals, or with non original coloured repro trim being sold as rare variants.
