Hi John , show us a picture of the front of it , perhaps someone will know it's model number . Also , and hopefully the other guys will help jog my memory , I recall using a website in the past that you entered the manufacturer and the numbers on all the tubes and it came up with model numbers from that manufacturer that used those same tubes , maybe someone can point you to that site ?
From your first pic I see that the power cord appears to be not run in what I'd expect to be it's factory location , I'd think it should be running into the empty hole on the chassis in the right had side of the picture (with a rubber grommet in the hole protecting the cord , of course) . If there is strange wiring it could involve someone in the past replacing the "curtain burner" power cord (if it originally used one as lots of small 1930s radios did) , this was a cord that incorporated a resistance built in to drop the 110 Volts to the amount needed by the tube's heaters . When the resistance cords deteriorate a common repair is to use either a resistor or a capacitor* to drop the excess voltage .
* capacitor being preferred as it doesn't get hot like a resistor does while dropping the excess voltage .
