My point was that, if the thing is a detachable element, then that CAN be the falcon, just without the thing. But if the thing is not a detachable element, then for that to not be the falcon would mean that someone heavily modified a 1300 in the exact same way that Han would do so 25 years later, which is equally ridiculous.
Although, that is a pretty blurry picture. I thought it was clearer than that in the actual film?
