Help - MCM dinner chair ID ?  

Slagelse Møbelværk. Usually see Erik Christensen offered as the name of the designer.

Does anyone know of any documentation that mentions the designer for this chair?

I have seen them attributed to Alfred Christensen, including some Bruun & Rasmussen listings.
Then, the owners of Slagelse Møbelværk were the Christensen brothers: Erik & Alfred. In house design.

Nice! That is very convincing.

Well I bought those 4x chairs and a Hugo Troeds table (2x leafs inside) for $1,300 (canadian). I'll need to rework the seats on the chairs, but I'm happy with my purchase.
