I got this nice little radio on that one auction site.
Very interesting to me is the fact that it uses a field-coil speaker. Unfortunately, the permanent magnet around the front of the magnet structure has deteriorated, and there are now hundreds of filings living inside the gap, preventing the speaker from moving. I have tried many times to remove the filings, but they are stubborn and I don't want to harm the speaker assembly. Help!
Here are some photos:
