Severin Hansen Sideboard? Niels Moller chairs?  

Can anyone tell me how to identify these pieces of furniture I inherited from my parents?  They purchased the rosewood set in Copenhagen in the late 1960's. Photos in the link below.

I do not see any identifying marks for the sideboard, but believe it to be Severin Hansen based on the design.  The chairs have been reupholstered so I am not able to see a mark for Niels O Moller - which I believe that they are.  I also have a table (extendable) that is currently being refurbished...can't find any mark. 🙁

Any and all help is much appreciated!
