Hi Maurice,
thanks for your offer! A black slider wouldn't be a problem, I will have to repaint the others anyway. After a good clean the BM looks almost mint now; would be great to get it working again.
I took some photos and wrote down the measurements. If you need more or better quality photos, just let me know.
Some more info: The wall mount consists of two parts. The actual bracket, which is screwed to the wall with two screws, and a cable cover that covers the - then on top - connectors.
Actually it's a pretty simple construction. First you insert the lower part of the bracket into the slots on the feet of the BM, then you push it up until the upper part locks into place (see photos). Therefore the two strips of metal that run from the lower slots to the main bracket have to be a bit flexible. Those are 0,75mm in diameter whereas the other parts are 1mm.
Afterwards you simply plug in the cable cover from the top.
