The famous stanchion bases topic once again... This time Bavaria 40 AC, 2001 vintage.
While searching for potential freshwater leak sources, I took a look at my stanchion base backing plates. What I found was apprx 20x60mm 3mm thick copper plates used as big backing plates. Would anyone know if these are these original design or already upgraded by p.o.? Yes - the material is most likely copper: I scraped the dark brown surface and revealed fresh coppery color.
My rationale says Bavaria would not have used copper (cost, electrochemistry) in such a place, but p.o. being electronics professional may have had a hands-on-supply of such material.
