As far as I know the Coronado sets were sold by the Gamble-Skogmo department store chain. I don't know who actually manufactured them, probably Wells Gardner, Belmont, Continental Radio & Television, and other private lable radio makers. The schematics are always listed under Gamble-Skogmo if you need to find one.
Is the speaker missing from the Silvertone? Is that why you need one?

Silvertone here it's a 10 inch PM type Primary impedence (not resistance) should be 5,000.
The loctal output tube 7C5 is similar to the octal 6V6.
More tube information here:

There are methods to determine what the secondary impedence (not resistance) for you to google, but most likely an efficient 8 ohm speaker would be fine. Do nopt operate the set without a speaker.
