The list gives the maximum parts each end fitting can take, so fittings can be added later; the drawings may show more items than can be fitted. Sheave slots are marked: outhaul in the O-slot, reef 1 in the 1-slot, reef 2 in the 2-slot, etc.
Inboard & Outboard Ends – B134 / B153
Items 1–15 are on the inboard (gooseneck) end, items 16–25 on the outboard end. The same drawing serves all four sections.
