Sony TV-511 Power Cord

[Deadvacahead]

I recently acquired a portable Sony TV-511 from a thrift shop for very cheap but it didn't come with a power cord. The TV functions with batteries but I would like to run it off of wall power if possible. The port for the power cord is odd and I cannot find what type of cord it is. Does anyone have any idea what type of power cord will fit the port in the photo?

Thanks!
