Yes, they look just like mine.
You may be confused on how they remove.
The hub is one piece including the "extension" for dual type wheels, all one piece, nothing comes apart, it's NOT a bolted on "extension" as you might guess at first glance..
The brake drum is bolted to the back of hub, only remove those nuts/bolts if you desire to remove the brake drum, which is usually never, new drums are real hard to find or non existent.
To remove the hub and drum assembly unscrew the hub cap, remove cotter key, and unscrew spindle nut.
Then pull hub off, outer bearing and flat washer will also come out and possibly fall out of the hub, catch them.
If you then want to remove brake drum from the hub, do so.
