Schematic
http://www.nostalgiaair.org/Resources/657/M0029657.htm
The good news
The cabinet looks nice. The pictures are still small, but you might not NEED to do anything to it except replace the grill cloth.
It looks like it might have a couple of globe tubes, always a plus. If all of the tubes you have are good you should be able to get the missing 2 for around $25.
It still has the original Mershon (copper) caps. Also a big Plus. Most of these were replaced and thrown away. This is also a minus since there is just about a 100% chance that they are bad. So don't plug it in again!
This is a family heirloom and you have the interest in keeping it and the ability to make a small investment.
The bad
This is your first radio. Please do not electrocute yourself. You do not have to look hard to find 300 volts on that chassis when turned on. If you have any doubts find a local repairman that specializes in OLD radios. That is why I asked where you are. Others here may suggest someone. A $200 RESTORATION would be cheap. A $1000 repair would be WAY too much.
As mentioned the caps will short the power supply when you find an 80 and install it. ALSO, that radio has line filter caps across the 120Volt AC line even when the switch is OFF. These are also very likely to short and may cause a shock or fire. Again, do not even plug it in.
The chassis is rusty. The shields are VERY rusty. If the rust has not invaded the chassis too much it can be cleaned and touched up. Some people paint them. That usually means that they are too far gone, unless they were painted from the factory. If only the shields are rusty they can be removed and cleaned up or replaced, which is also a consideration for the entire chassis. Sometimes a nice one, less a cabinet becomes available. Occasionally it has even been rebuilt.
You need a speaker or at least a new cone.
The rust on the chassis causes me some concern for the cabinet integrity since moisture also causes the wood to delaminate and joints to fail. But this should be easy for you to check.
You might still be able to get an acceptable grill cloth from these guys:

Don't wait long to order.
If you elect to sell it, I would be interested in the cabinet.
Good Luck
