It's B&O alright. Not sure for what, though, but could be a RIAA, so perhaps an input adapter for a TV or a tape recorder. Late 1960s or early-mid 1970s, I'd say. And the 56K resistor has a bad solder joint. Perhaps the reason it was replaced. Martin

Thanks for the answer. Looking closer I can also see that the DIN connections are definitely not B&O standard connected. It seems that pin 1, 2 and 4 are all connected across the 2 DIN plugs, and pin 3 are connected to pin 5 on the other connector.
