Those are Vintage Carefree parts.
Yes, those are Vintage Carefree awning parts.
Top and center: the 3 pieces with the rectangular holes are sliding locks that fit inside the main arms. One has a post and ther other 2 have posts with them but they are not installed. The post goes at the top and points toward the trailer and that is what you hold on to slide it up and down. These slide down over the travel hook when the arm is closed to lock it in place.
Top right: is a main arm lower support that the arm pivots on and the angle brace fits behind when it is disconnected from the arm and stowed for travel.
Right side: 2 pieces are the stops that go on the roof over the awning channel for the tube to rest against.
Bottom piece I don't recognize.
Lower left piece I don't recognize.
Left side: those 2 pieces are the hook part of the travel hook.
Upper right: Are the 2 U shaped pieces the travel hooks fit into. These bolt to the body half way up the sides and the travel hook slides into them and can be adjusted in and out to make the arms vertical when stowed. A bolt goes thru both pieces to lock them together.
