In a group a parts I recently aquired, I got an early chrome valve cover
that has a strange vent on one end.  The vent is about 1" by 2" and is on a
bout a 30 degree angle.  I was wondering if anyone had ever seen one like it
before? It appears to be after market but I'm not sure.  thevent is chrome
and matches the cover.  I tried to attach a pic of it and send to everyone
but it has not yet made it.
