Good news: We’ve been able to source the type of hood I was looking for:
More or less new, no scratches and super-transparent (not a given for 20-year-old Plexiglas)
It has just been delivered from Germany, where it was in storage for the last decade and part of a TWIKE easy which was exported to Germany from Switzerland.
Welcome back to Switzerland!
I’m super happy.
