If you can get a model number off it you may want to send a picture to the Radio Archives' Antique Radio Gallery because they don't have this model in the gallery yet.

Check out the Antique Radio Forum
www.antiqueradios.com
and the rec.antiques.radio+phono usenet newsgroup archives at
http://groups.google.com/group/rec.a...n&lr=&safe=off
Both of which are searchable for "coronado", your model number, info on restoration, recapping, sources for tubes, info about old record players, etc. etc.
Likely it plays 78s and has a crystal cartridge which is trashed due to its age. What Donny said about recapping the radio and just using it for that, is good advice.
I think there are tutorials on restoration at
www.nostalgiaair.org
if I remember correctly.
