The coil wire does not look burnt so maybe, just maybe if you are lucky, it has rotted or broke right at the top.
If not.....you seem to have a very good intact cone and the spider. Try to remove it without damaging, if you intend to press out the centerpole in order to remove the coil and rewind it.
And....copper has been expensive for quite a while. So is the magnet wire, being practically copper by weight. Pure copper on Amazon is $25 a pound.
As a commodity, it is about $5 a pound.
And you need to draw the wire, coat it with lacquer......
The resistor on 20/70/90 almost always double in value. I have seen maybe 2 or 3 open ones, but if not, teh value is 70 to 100% up. With a notable exception of large divider resistors (10K/16K, a 2W and 1W ones): the large one almost always (in my experience) goes down.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
