Weird Moller 71 or something else?  

Something else based on those corner blocks.

And the shape of the back and I think the legs and sides of the frame too, right?

No M

You probably think of the Kai Kristiansen for Korup. They look somewhat similar. Maybe that is a starting point.

Yes the joints get me, I've never seen it on a chair of the similar period before. Maybe this is a copy from a much later date?

I'm afraid that this is neither Arne Hovmand or Moller.

I have some information on this buried somewhere. I'll try to take a look tonight.

The chair is by V.S. Andersen for VSA Mobler. The only other designer I know of who did design work for them was Kai Kristiansen.

V.S. Andersen also designed this chair, which is frequently attributed incorrectly to Madsen & Larsen.

And VSA M

It seems likely that VSA was influenced by Kai Kristiansen who, as pointed out, used these mitered jounts elsewhere. Or maybe it was the other way round.

I see that the Danish Furniture Index lists a number of designers that worked for Schou Andersen, now that I have thought to check. In the small catalog I have, it shows only designs cited to VS Andersen and Kai Kristiansen. The Kristensen dining chairs shown are all familiar ones.
