Maybe, it's also possible SS never actually had access to the scans as Winston studios made the prototype which SS then produced exact copies of, this is why the ADI bios had no lenses as ADI sent SS examples without them. Still SS have a good relationship with a lot of studios, maybe if they asked Legacy for access to them they would be allowed to use them. This could of course add extra cost but I suspect people would happily pay more for near perfect representations.
All speculation anyway and this looks cool enough from what we can see so far, that maquette just raised expectations due to how good it was.
