<VV> engine lid support

[Roger Gault]

Marc,
Actually, things are more complex.
"Austenitic" stainless steels (mostly 300 series) are usually not magnetic.
Most other stainless steels are magnetic.
The Austenitic stainless steels are by far the most common, but there's
plenty of 400 series stuff out there.

To make things more confusing, some of the Austenitic stainless steels
become magnetic (to varying degrees) when they are worked.  So, the
stainless steel trim could be 400 series, or it could have become magnetic
during the forming process.
