I was watching Once Upon a Time Part 2 on the Decades marathon yesterday and noticed when McGarrett visited Walter Grant's mother and brother that in the background above the china display is the same portable radio that was used on Gilligan's Island, not just the same model but the actual prop, the stock AR-851 Packard Bell doesn't have an antenna or handle but was added to the Gilligan's Island version and this one also has those parts they must have come from the same prop department.
