As for being bronze, short of getting it tested, appears to be bronze compared to other definite bronze pieces we have that have been subject to long exposure to damp, dirty conditions. Of course a bronze statue that has been cared for over the years looks much better…
Short of a metallurgy test of course.
We are in the NYC area.

That is not what bronze should look like !! Can you take a pic of the bottom !!
What is your location ?? Molten metal is not something that is worked by hand !! The mold is what would be hand done !!
