Anomaly?

[Egenolf]

As far as I understand the interior trim convention, the „lower shell“, you have mentioned in your first post
is identical with the front seat frame and trim of the chart.

In the cars of 1956, these items have the same color as the seat bolsters.

In the cars of 1957, the front seat frame and trim have different colors.

1M6E of 1956 have white leather for front seat frame, trim and the seat bolsters.

In 1957, the colors are green leather for the front seat frame and trim and white leather for the seat bolsters.

edit: Sorry Roger, now I understand. The problem are the upper and the lower frame and their different colors.

Maybe, the backrest is sometime changed.

I have no other explanation.

Who knows what happened during the life of the car...It could also be a factory error during the installation of the backrest.
