I dont think the number would be covered, but I'm not sure.
I don't know if you've already done this, but try undoing the mounting bolts/ nuts for your bisector / brake adjuster. soak around them with CRC and try chasing them back out of the backing plate, as you try to draw the brake drum off. If there is a groove or shoulder in the drumthis may make it easier to get apart. Another thing you might try is bolting a bit of steel bar accross a couple of you sprocket mounting holes, so that you might be able to rotate the drum.
You can put a shouldered plug into the end of the axle tube to pull the hub against, being carefull not to do any damage to the thread of the axle tube. I would remove the outer bearing first.(I note you have) Then you can "woble " the hub as you pull it. It's a frustrating struggle, but be patient or you'll damage something, thats hard to get.
I would get hold of a good fitting tool to back of that brake adjuster. the force you put on it maybe enough to nudge the shoes into moving, and if you can back off the adjuster, it gives the shoes some where to go.I would do this first.
When removing rivets, note where the flattened ones, and the flush ones come from. there is always a reason. Something won't fit later.
When rebuilding the bisectors, be very careful at assembly. They can be assembled wrong and in that case will be ineffective.
If your cam plate is rusted on the working edge it can be built up with weld.
