Q: Is the metal on this barrel stainless steel?

I've been running this barrel for 5 weeks now and seems to be running good. Metal appears to be stainless steel to me since it seems to be heavier than what aluminum would be.

Q: How to assemble Barrel

It is assembled. Tub and lid. May have to screw on knob to lid.

Q: I am looking for a 3 lb barrel for a national geographic rock tumbler. Fo you have any idea where to find one.
