Not Borge Mogensen 3238 chairs....  

I posted a few days ago about these mid century Danish leather buckle strap chairs. I looked online and, being a novice, immediately thought were Borge Mogensen. Apparently they are NOT consistent with his design.
I bought the five of them at an estate sale where they had been stored in the garage - look to have been there for quite some time. They are definitely NOT new. I could locate no markings on them. As you can see the leather was very dry and discolored. I have only worked on the one so far. Just cleaned it and conditioned the leather with 100% pure Neetsfoot oil as advised by @leif ericson Amazing how soft the leather got with just one application!
So what are they???? and does anyone know what kind of wood they are? Close up of wood below.
