Børge Mogensen sideboard with a bent back: advice please  

Thanks for the thoughts, glassartist and leif.
I moved the sideboard inside last night (it is a bit tight in the kitchen, but better than the frigid garage), and was able to examine the piece a little better. There are four loose shelves in the left compartment and three sliding drawers on right (the shelf on the right from the previous photo is now one of the four on the left).
All four shelves are original solid wood core with a thick veneer finish (I think beech). The drawers are solid wood, same type as the shelf veneer. Leif's catalog drawing shows two shelves on the left and four drawers on the right. Either my config was ordered this way, or someone swapped pieces with another sideboard after purchase. 
So, if anyone out there has a Mogensen 5' sideboard with five drawers and no shelves, I'll be happy to swap you two shelves for a drawer. 🙂
On another note, the catalog listing in tchp's earlier post notes that the base comes in beech, oak, and teak. I'm not the best wood IDer, but I'm sure my base is not beech, and think it looks more like aged oak, rather than teak.
