Early Hub Identification

NOT REALLY A QUIZ , JUST TRYING TO FIND OUT WHAT THESE FIT. ANY EXPERTS OUT THERE?

Barry, I'll make some guesses if I may.

Left column, starting at the top: 1-?, 2-?, 3-looks like a pre-Timken 1920 Excelsior/Henderson front hub. 4-looks like a Henderson pre-Schwinn front hub.

Middle column, 1-?, 2-looks like a H-D JD era front hub, 3-looks like an Excelsior/Henderson Timken rear hub but it isn't spined for the sprocket and brake drum.

Right column, All three look like sidecar hubs. I have an H-D s/c hub that looks just like the middle hub.

Thanks Eric, very helpful response. Most of these hubs came out of Kenosha. Maybe the unidentified one are Pennington!
