That is the old direction reverse for the original Deutz engine, however it was still used as the gear clutch for the Scania. The other little wheel further back on left is the engine revolution control. Also being for the old Deutz but still in use for controlling the Scania.
Despite been laid up for over 11 years everything worked beautifully on her and if I would have got the work for her in Finland as we hoped for she would have been repaired back to service. But unfortunately that didn't happen.
My colleague wrote a blog of the whole project, her revival and eventually of her last voyage we all did together.

If you look at this pic http://www.shipspotting.com/gallery/photo.php?lid=3331632 it would seem that may be the 'throttle'.

Hi Denis, I do not know what the purpose of it is or has been I guess it has been used in connection with the original engine.

What that vertical column with a wheel on it was possibly used for?
