Unfortunately, from what I understand, finding a usable speaker of this type is next to impossible. they use old style pot metal which warps and cracks. The method for restoring is to use a modern permanent magnet speaker with a impedance matching transformer, which will actually make this radio sound better as the original speaker was already dated when used. I do have a speaker shell for a 511 which I could put the original speaker guts into just to keep them.
Here are some pics of my 513.
