Great, this quite dramatic improvements, regarding Cint! Here just
the materials on which my coils are wound, and the wall thicknesses:

wall thickn. 2 mm 3 mm 4 mm 3 mm 8 mm

Apart from measurements for the short d=38.5cm coil (not in this
table!), I hope to make better measurements for big coil Sk-B&W too.
Cheers
