My old Mercedes that had rear drum brakes had three evenly space
threaded holes in the face of the drum.  You could thread bolts into
those holes, and then tighten them evenly and they would push against
the flange and press the drum off.  Nice touch, I've not seen that on
any other cars, but I'd guess you could drill and tap some holes to do
that once you got the drum off.
