Older DS II with racing rig?

[redtailseven]

I have purchased a Daysailor with more rigging than I have seen before. It was built before HIN's and has a plate with model #6061 and a SN in the 3000 range. It has a traveler across the CB trunk and an enclosed cuddy with canvas snaps around it. The mast is the most interesting feature. It has a taper aboove the spreaders and the halyards ar cables that run through the mast and exit at the shoe. The step is adjustable. It was sold with a Holsclaw trailer said to be original to the boat. I'm expecting 4 sails, including a genoa (were stored somewhere else). Obviously this isn't the sedate '77 II that I had a few years ago. It must be a racer. I hope I didn't pay too much for it, its in tough shape, but what exactly do I have?

A look at the tech info section suggests that I should have posted in the DS I section.
