Thank you.

My German is not up to the task, and translation pages are not being helpful, but "hauptkupplurg" is clearly a massive clutch; "hauptdrucklager" a bearing block or flex coupling.

The next item to the left, ?Wellenbramer? I don't grasp. A tachometer maybe?

In any case, my primary question is answered: Diesel, MG & prop are lined up on one axis, with no gearing or cross-shafts.
