The San Diego Aerospace Museum is interested in the chronology of the
development of aircraft fittings, fasteners and associated hardware
with the primary purpose of accuracy in restoration and reproduction.
e.g. when were the following first used in a/c production:
     elastic stop nuts
     swaged cable fittings
     cannon plugs
     dzus fasteners
     rivets:  round head
              brazier head
              flat head
              countersunk
please reply to (yon@rohan.sdsu.edu) and to the newsgroup.  thanks.
