🔎 UNIDENTIFIED I need help identifying these balls

[Truth]

I need help identifying these balls. All I can see is on the small one I can make out some writing “Monarch ball” The larger one I can make out “RATMA” and it also has screw grooves in that one. I found these I have no idea what they are. Thank you. The first one is large then medium and small

Maybe somebody made a gearshift knob out of it. This one doesn't have a hole.

Simiar in size to some antique wrought iron I have with balls on the post. They have a name on them but its under 100 years of paint.
