The cones are not too hard to make. I use the heaviest paper I can get from the office store (42lb ??).
The pitch is different from later speakers so an off-the-shelf cone replacement will not work. If you remove the old one intact, you can use it to adjust the pitch of the replacement.
On this one I used felt, but the same cone can be used with a chamois surround, or pig skin, which is what I use.
