I am not sure of the brands, but I have seen speakers with ships and dancers bring a fairly good price on eBay.
Re the coils, the only thing I can recommend is that you can peel away the paper wrap and inspect the coil for a break, start unwinding and hope that the break is only about a few layers down. Otherwise rewind per Chas
+1 on Chas, the "Magnetic Reed' speakers, the coils are not wound around the magnet, therefore polarity is not as much of an issue in terms of losing magnetism.
I have used an AA5 transformer and modern speaker. However, this may not work well with anything less than 71As at 135V or higher, as 201s and even 112s put out <35mW at 90V, but works well on my Radiola 17, 18 and 60, as the 71A puts out about 0.7W at 180V.
