It'll be interesting to see those results. Could be that the same
materials used for flexible shielding will turn up (check Chomerics
for flexible shielding "finger stock"). My guesses would be
phoshpor-bronze or perhaps beryllium copper. Although I don't think
the originals were made of this, perhaps even stainless steel might be
a good substitute.
