Maury shared these hubs for sale. They are Allstate hubs and, likely, a very early set. My guess is the these were likely built by Husky/Dualmatic, but I am not familiar enough with hub innards to say for sure. I can’t quite find a brand-name hub with the cover that looks quite like this.

“These hubs are all complete and turn freely. The dial is heavy case aluminum. These only work with threaded axles ends. I tried putting them on the later snap ring style axle and the snap groove does not protrude out. Outer case was chrome originally. They seem like a really well built early twist lock hub. Asking $150 obo plus shipping. I also have a picture of how the innards went when I took them off the axle.”
