It's possible you have a rare "Velvetone President", made by a long-expired Canadian company called Kitchener Electronics. They also made amps under the brand name Kiel (KItchener ELectronics).
Dunno what it could be worth, but it might be a cool-sounding amp once you get it up and running again.
Not enough valves to be a Gibson GA-20. On the other hand, the GA-14 and later versions of Gibson GA-6 match the valve layout in your discovery.
IMO, the electronic design does seem to owe quite a lot to early Fender Deluxe Amps.
What is the writing on the capacitor nearest the AC power lead? It looks like "HUNTS Capacitors, Made In England" then, a part number. Is this correct?
The voltage selector pin base suggests an export model from wherever it originated.
P. S. - Googling "President guitar amplifier" brought up Velvetone and some Canadian-built Hawaiian guitar amps a la Magnatone.
