Match one to many where key has 4 variables

* My data sets contain
data from an archaeological site and the first four variables in both tables
tell the location of an artifact in a site. The first table is the artifact
table and has data on 23,000 artifacts with several artifacts coming from
each location and listed seperatly. (there can be as many as 50 entries that
all share the same first four variables and same location). The second table
is the context data and contains 1,600 entries in this table there is only
one entry for each artifact location. I wish to merge these tables so that
the correct location information will be coppied into the first table.
