I'd be wary and looks too good to be true. Also could be someone that inherited it and has no idea what it is. Ask for specific pictures and plenty of them. If they pulled the pics off the internet they only have what they have. Asking for specific pics is a way to determine if it's the real deal. Talk to him on the phone. I sell a lot of stuff on line for old friends with no internet skills. My phone number is listed and I take calls. If he wont't take a call then I'd be out at that point. He contacted you which is a red flag for me. Good luck.
