I have a Harken Main Sheet traveler for sale. This was removed and rebuilt with the intent to reinstall during refit but ended up not using it. The car I believe is a Midrange Windward Sheeting CB Car (HAR1635) on a 5 foot track with End Control Blocks, See Pics, I dont have any control lines and the system was well used but all of the block and jaw bearing have been replaced along with new balls for the car. Ready to instal. Track has a very small curve to it as it was mounted on a curve but would straiten with out a problem. Not sure what its worth. I'm thinking $200 - $300. Make a offer.
