Mid Century Modern teak curved back armchair, dining chair, Danish? - ID help would be much appreciated  

Well, it’s less of a copy although the angle of the rear legs is similar to the 42 chair and the back Rest reminds me of the Compass. But I‘ve never seen this one before.

@amber5. According to a seller this  is  a "rare" chair designed by Ejvind A Johansson and made by Gern Mobelfabrik. Denmark.

Attaching image of stamp which is basically illegible.

Clearer stamp from a Gern cabinet.

@lexi, found it, thank you very much!

Apparently, Ejvind Johansson is also referred to as the most famous unknown designer:-)

He once was head designer of FDB so he‘s not obscure. 

One way or another, I love his chair; it is very comfortable as well.
