Sailfish rigging

Refinishing/repairs nearly done on Sailfish (circa?..) Question about rigging…. I see a lot about Sunfish, including Signal Charlie’s book (thank you). Do Sailfish not have a main sheet swivel/ratchet block or cleat? This has only the cleat on the mast step. Am hesitant to add without clearly know what’s where on the insides and we didn’t have to go that far.
