Help confirming boat identity

I bought what was billed as a 1968 Day Sailer off of Craigslist yesterday and the more research I do the more I think it might have been misidentified, a clone, or perhaps that it's been modified or heavily rebuilt. There is nothing on her that gives me any clue about the manufacturer including the pre-1971 hull number. It looks, to my inexpert eye, like a Day Sailer, but there are some differences like a lack of thwarts, no lever for the centerboard, the mast not going through the deck to the bottom of the hull, etc. I would deeply appreciate it if someone could help steer me in the right direction.

Hopefully an imgur album link is acceptable because I cannot figure out how to embed images that aren't massive.
