65 Commando stock brake set up

They actually do fit, at least on my 65. Here is a picture of one holding the shoe on the front.

I'm confused about the hub and drum assembly. This sure isn't what parts books show as a replacement. The number on the drum is 720087. I'm going to get lucky, but drums are ok to put back on. Is this drum/hub assembly common or another oddity on my car.
