It looks old and does have some "correct" features that you want to see on old banks. The casting grain is very fine and not pebbly or sandy that cheaper, reproductions will have. The slotted hardware is a good sign since its really rusty and hasn't been replaced. Phillips head screws showed up around 1940 so most banks sporting those are fakes or reproductions, which are not the same thing. fakes are junk, repos have collectible value, just not as much as an original.
The file marks look good because these banks were hand finished, not hit with a bench grinder. The gap between the 2 halves is tight with some gaps. Not all banks are joined perfectly so some gaps are okay, huge ones are a red flag.
Ill let my old man take a look at the pictures later. He might recognize the maker or style and should be able to tell if its original or not. If i get a chance, ill take a picture of his office for you.
i almost forgot, the feet! The wear on the feet indicates many years of being moved around on dusty surfaces. Bronze isn't soft but that type of wear is hard to fake.
