Fuel Master W/H date

Fuel MAster FM-50-C oil-fired water heater. Serial # K16B3056. This is a new one for me, I never heard of Fuel Master (Heat Transfer Product). Any idea of a date of manufacture? It’s an old one.

If it’s an old one, especially oil-fired, it’s probably a major local brand that went out of business decades ago when the owner died.

That’s about what I figured. Can’t get any info on the old POS anywhere. It didn’t work anyway :smiley: . Thanks for the reply Russel.
