Thank you all for your kind comments!
Another detail that I didn't mention so far, is that the console can be split into two parts, so that we could move it into the house, to the the first floor, without the help of a moving company.
The workshop where it was manufactured has a large CNC machine, indeed, but it was only used for this support:

All the rest was made with classical woodworking machinery.
The consoles of Cavaillé-Coll have undergone some evolution during his life as an organ builder. Unfortunately there is little known about the craftsmen who made the casings and the consoles. I recently had a discussion about this topic with Gilbert Huybens, who made the first inventory of Cavaillé-Coll's instruments.
This console (the orginal one) dates from 1880. By that time, all his consoles were constructed in the same way. Only the details of the mouldings and the frames of the panels could be slightly different.
