I had a 401k with an old employer over 17 years ago. The company has since sold. It was a radio station owned by a company in another state. The company sold all stations and newspapers. I received a statement years ago with no phone # or address, just saying benefits paid at retirement would be $35 month. It is not much, but would still like to roll it over into something else. Thanks for any help!

This sounds more like a pension plan, or perhaps profit sharing, rather than a 401(k). I suggest that you try and locate the HR department for whomever currently owns the radio station and see if they have employment records going back that far.
