Clips - Tent, Spinnaker, or ??

I have a '65 DS1. It came with a spinnaker and associated sheet and other lines. It also has some yet-unidentified clips on each side of the boat, one at each aft corner and one midway back, somewhat near the jib blocks. Here are some photos.
I have very limited experience with spinnakers in general and none on a Day Sailer. I'm wondering if these clips are for the spin sheet/guy line in place of an actual block. Has anyone encountered this setup?
My other thought is that the clips are related to a boom tent or similar cover. For those who have spinnaker rigging, are the aft clips about where you'd put a block for the sheets?
Thanks for any help,
Brian
