Well, I was wrong (again).  I had long assumed that the cases were magnesium,
since they were so basically similar to the TypeI cases, and so unlike the
TypeIV cases (I have one of these, too).  So I went out and took a sample of
my 1986 2.1L waterboxer, and tried to ignite it without much luck.  I will
believe.  Again I have spoken too soon, assuming things I did not know for
fact.  Oh, well -- I do this a lot, and now know that none of the Vanagon
cases are suitable for campouts.  Thankfully I still have many junk typeI
cases lying about for this use.
