I don't really see any hint of it being a hand made hammer welded head, which would hint of being older than your town. It looks factory made, but it still can be from the mid 1800s industry in your town.
one interesting thing worth mentioning: A person who made a living with an axe, is less likely to abuse it by hitting the back end with a sledge hammer, or using the back end to bang on a steel wedge to split wood. The mashed ones are usually a homeowner who also used the axe as or with a splitting wedge, which is not good.
Yours does not look like it was used that way, but it proves nothing.... except it hints to someone using it to fell trees, not primarily making firewood.
