If you do get your mumetal, be sure not to fold, spindle, mutilate or
heat it past the manufacturers spec's.  Mumetal looses its shielding
ability if misused. It's typically pre-formed and cooked in a pre-
determined shape so as to avoid the possibility of user misuse.
so I guess the bottom line is - BE CAREFUL WITH THE STUFF - or it won't
do what it's `sposed to.
