As the EF39 can work properly, as you've proved, unless you've got a glut of them it would be worth using a metallic paint to replace the screen - I'm sure someone can suggest something suitable. Clean the earth wire first to ensure a good contact. If necessary extend it with a bit of thin wire, loop it round the glass at the bottom, trapping it in the crack between the glass and the base then, while it's pulled as tight as possible, run some solder over it.
If it snaps off or isn't present, get a length of very thin tinned copper wire (or use one wire from a piece of stranded wire) and wind it round the earth pin, attaching it with a very small amount of solder then run it up the side of the base and loop it round the glass at the bottom, trapping it in the crack between the glass and the base then, while it's pulled as tight as possible, run some solder over it as before.
It wasn't uncommon to see this trick done on many radios in the past.
