Okay, if you're not going to run, I'll offer an opinion with which a guru might disagree so wait for some other feedback.
No matter how old the business, it would seem that they should be registered with the secretary of state if it is a 'legal entity'. Even absent a registration, they should have some documentation such as articles of incorporation, certificate, business license from the locality, etc. In the absence of such documentation, I'd presume it is a sole proprietorship and would file as Joe Customer conduction on his own behalf.
