it's a flying cloud as already pointed out but i'm not sure it's a '56. do you have the VIN # located near the door?
i have a '56 and my access panel is on the curb side, yours is in the rear. mine was made in los angeles, yours was made in ohio so that could have been a difference between the two, not sure. the VIN # will tell you for sure, if you can look it up and post it, that would be great. the street side windows are different as well. my guess a '55 flying cloud.
your cloud as is is worth around 3K or so, probably worth 20kor so all fixed up. you could easily spend 10K-15K in the restoration process if you did more of the work yourself.
i'm in the process of a shell-off renovation, here's my cloud for reference;
