There is German company I've got belts for Awia Cassette Deck, Dual 55 and Telefunken portable reel to real. I'll look out for contact details if you can't find anything.
You can glue a cut belt with superglue, but likely it snapped.
Electret inserts are about €1 or less and spec /size not critical, but it is most likely a dynamic (moving coil) of about 200 Ohms if early 1970s, in which case replacement for capsule is harder, though any electret with built in battery or cheap dynamic will work. Crystal or ceramic is unlikely.
Edit: the Radiomuseum example is an electret. Any capsule should work. It won't be a real "condenser" microphone as those are professional and internal higher voltages rather than 1.5V to 6V via a resistor on an electret.
