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.
