The general legal answer is that if the assets were not dealt with either privately (e.g., assignment to a creditor in satisfaction, or claimed by a creditor as part of a secured transaction), or publicly (e.g, bankruptcy, assignment for the benefit of creditors), it passed to the stockholders of the company, subject to the claims of creditors, i.e., actually owned by the stockholders but always open to some legal proceeding by a real creditor. From there, who knows; e.g., there might be a difference depending on whether it was a public or a private company. Suffice it to say that no one on this list working with the information at hand can give any advice that you would want to stake your life on.
