Moin,
thanks for the input lads. Iīm considering to agree with SSB.
Thanks to RaptOr Iīve checked all my photographs from my last visit to U995. I didnīt recall to have seen any installation near the ladder. But there it was, shot by myself. Stupid me.
So, I decided to revert to the stock model and added the labels only.
Donīt know whether thereīs a way to get them lit in an appropriate way. So, UFN they will stay dark.
