Thanks Lads.
During the life of the Europa in my possesion someone used a orbital type sander to rough up the paint. I reckon for a re-paint. But, they, the sander, didn't remove the molding/frame/trim.
So now it has sanding orbital marks embedded in the aluminum.............ugh. Yes, they can be buffed out and re-anodized.
Hence my question on the aluminum bits. I did get additional info from one the Europa loyal and yes, a type 54 Europa is the the same window frame. Any and more info is always nice to have.
