Here you can see what i repaired and restored up to today. A lot of text documentation is missing here, most stuff currently is just a bunch of photos i took during the work. Having an easier way to document everything now might give me a bit of motivation to really do this soon.

For the old overview, see below. This new list is sorted the same way like the navigation menu, but it is not limited to 10 entries. The entries found in the following list are sorted by their last modification date, so the stuff i worked on recently can be found on top of the list. Some items had more than one repair so far, there don't exist multiples entries, like i had this in the manual list, but they appear as one entry in position of the most recent activity.

This will live as long as i didn't create separate pages for those items.
