Would appreciate help in identifying the lovely Danish (I believe) Dining Set  

I picked this up a few weeks ago at a sale, and though I'm somewhat familiar with MCM furniture, I can't seem to place this maker.
Here is what I know. There are six chairs, two of which have arms. The table top appears to be formica and has a leaf. All of the chairs are marked (stamped) with "2206" on the bottom. There are no maker's marks on the table.
Here is what I was told. It is Danish and Walnut.
Any help would be appreciated - it's in super shape and has the original green upholstery underneath.
THANK YOU!
