On the two examples the primary thought is that the front brake has switched hands.

now, even Merckx changed his “handedness” over his career.

Weinmann was opposite of what Campagnolo did and the later group think was to emulate them.

and here I thought you were going to show a Schwinn Paramount where the top tube cable guide bias was to the drive side when the model used Weinmann centerpull calipers and depended on no stops when using Campagnolo. Running the housing uninterrupted from lever to caliper.
