What exactly is this coachbuilt Cooper?

An interesting coachbuilt Mini has turned up in Germany. Said to have been delivered new in Barcelona in 1968, this Mk2 Cooper is an early Authi-built Spanish car. From the advertisement: "This Spanish-built Mini Cooper is one of only two believed completed with faux 'cane furniture' side trim, the other being in a museum in Barcelona. The car had been disassembled prior to its acquisition by the owner and is now partially restored and in an excellent state of presentation. Accompanying documentation consists of a French Carte Grise and sundry invoices from Morisse Nayrat and British Car Centre for works carried out and parts supplied."

That does look like a nice car indeed with some interior touches unseen to me before. How about the leather-clad lids on the door pockets? It does also raise some questions though. Is the other car mentioned perhaps this Mk1, found in Barcelona a few years ago? Could the wicker work be the work of Taka-Hira of France also? What's the Verdun Automobiles decal doing on the back? And why is it advertised as only 'partially restored'? See the ad here.
