at a minimum, reversing the date sort (as matt suggested) would help
tremendously.

(does rather make one wish that date was a sort key in this data set...
find by part-number and do a backwards read on the chain...badda bing, badda
boom, eh?)

I wonder, however, if suprlink might be useful in this situation.  it's made
for doing many-to-one links.  a visit to:
http://www.robelle.com/ftp/manuals/suprtool.pdf may prove enlightening.
