Try this:
Code:
#!/bin/bash

awk '{print $1}' PUR.*  | sort -u > keys  #save all keys
while read k ; do 
  out="$k"
  for f in PUR.* ; do
     a=$(grep "^$k " $f | awk '{printf("%-4.3f %-4.3f %-4.3f", $2,$3,$4)}') 
     [[ -z "$a" ]] && a="   -     -     - " 
     out="$out $a " 
  done  
  echo "$out" 
done  < keys

It assumes you can glob all inputs with PUR.*
