It doesn't ring a bell... but I have been wrong before!
As far as I know... B&o made a "table" for this series that is rather rare, but I don't believe they ever officially had any mounting brackets, vertical or horizontal... the horizontal, of course being redundant.
Keep in mind that functionality of the CD is the problem here.
With that said, there was a third party source that apparently made some brackets.
Take a look here for further reading.
