Hi Raymond and welcome!!!
Throw some batteries in that bad boy and you'll be ready for the beach or a camping trip!!! One a bit of a more serious note I'd recommend replacement of the paper and electrolytic cap in this guy. If not and you got some leaky ones in there it will run down your B batteries in a hurry. That gets expensive!!!
As for the original battery I doubt you can get it anymore and if you could it would run like $40-50 bucks. There's Bill the Batterymaker. He can build a original looking battery box to snap in your new 9V and D cells and it will plug right into your set. Don't know what it would run but he does nice work!
If you have milliamper meter hook in series with your B supply. If all is good (no leakage from your caps) it should draw about 8.5ma or so with 90V B and 1.5V A volts. The service into can be found here:http://www.nostalgiaair.org/PagesByModel/303/M0013303.pdf That's for a 39-71 there about the same.
Have fun w/it
Terry

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
