We've found this in my wife's, Grandmothers attic after she passed. It looks to be in very good condition, so we're trying to decide if we should keep it or sell it. Part of that will be determining what it actually is

This is a picture that my wife just sent me to do some research on. Unfortunately she didn't look for a model number tag anywhere, but I'll do that when I get over there too. In the meantime, I thought maybe the experts could help out

If anyone can give an estimated value of something like this, that would be great too.
