RY Mobler and Hans Wegner  

I am about to buy a teak cabinet and small chest that are marked RY Mobler - Made in Denmark.
The seller seems to think they are designed by Hans Wegner. I do see the same pieces on Google images attributed to to him, but it seems to me that ALL RY Mobler vintage items are attributed to Wegner (online dealers) anyway -
It doesn't seem possible that he designed all RY Mobler furniture - but maybe that is what the RY means. I can't find anything online about this - can anyone educate me on this?
Thanks
