Here is the bottom of the mast and the fitting thanks guys!

Greetings all! New member here. I just acquired a venture 21 from a fellow who’s dad was restoring the boat. Unfortunately some of the hardware is mixed up/missing. I’m trying to figure out how the mast attaches. There is a U shaped hinged fitting at the foot of the mast that swings with a metal peg...
