Regarding that the photo is taken in Norway you might think that this is a Kambo built cabin. However, it seems to be a ventilation window mounted in the door and that is, as far as is known, not part of the Kambo design. Note the special grille. It is the Master-Front, an extra part sold in the '50:s. It contained 2 sets of chromed pipes with 6 to 8 vertical pipes each. They were placed behind the original grille and should, according to the commercial ads, only take 5 minutes to mount. The result was a front with a more luxuary approach. A big thanks to Kåre for the picture! Thanks also to Ulrik for the picture of the grille device.
