Yep, I agree that it is in all probability a cast aluminum pot. I even went so far as to go dig out some of my old pots just to compare. This is really an old pot. I also have a full set (20 + piece) of Magnalite auminum pots that are over 35 years old and still in daily use.
Your pot will continue to cook as always with no impact on food flavoring. Fire will only damage it or destroy it. The pot appears to be a 4 - 6 quart capacity. Were it cast iron, it would be quite heavy. Also, I don't think it is possible to hand clean a cast iron pot to get that shine that this pot has. Sandblasting would be necessary to do that.
Suggestion: Enjoy your clean pot and DIL. lol
