Need an apparently-discontinued moulding profile; where to look?
take a look at this suggestion from ask this old house:


  When none of the offerings at the home
  center or the lumberyards measure up,
  then it's time to go the custom route.
  A millwork shop can make special
  "knives" and turn out an exact
  duplicate of your existing moldings.
  The problem is, you have to pay setup
  fees, which increase the linear-foot
  price significantly and may not be
  cost-effective for a small order like
  yours.
  
  The way to avoid those charges is to
  make your own profiles using a table
  saw, band saw, and router. On the next
  page, you can see all the steps I
  follow in order to copy a short piece
  of baseboard cap. The process isn't
  difficult, as long as you're familiar
  with and respectful of these powerful
  tools.
