hard top

Hello List,--I am trying to identify the hardtop I have for my BI. I have 
contacted a couple of sources who say they might have the rubber seals but they 
need to know the original manufacturer.I can find no marks anywhere. Sources 
ask if it is a Parrish or Smoothline. If I do have an original factory hard 
top, 
how do I identify it?Who made it? Any thoughts out there?     Bob C in KS
