The gas spring under the trunk lid of No. 168 didn't work properly. So the owner went looking for a replacement and found it. At the Laman company in Amsterdam, www.laman.nl , he first ordered the original Stabilus spring of 15kg's. This one proved to be slightly altered, as a result the lid didn't open fully.
Later he ordered the same spring with 20kg's of pressure, the Stabilus 2236 LN. This one worked perfectly and appears to look original as well. As soon as we have a picture of it, we will post it.
