that helps a lot. it shows the construction which is correct. I am confident is saying 100 percent a trade axe. So these "fur trade axes" came mostly from 3 sources. the french, spanish, british, and then the colonies who started to copy them at later dates in much much smaller numbers. A general rule(but not a exact rule) is the ones from the colonies and british seem to have a top line that slightly curves down. Yours is relatively straight and with a wider blade, so I think it is safe to say for sure this is a imported trade axe from either the spanish or french. The french are more likely due to them being one of the largest supplier of these things, yet your location makes me think spanish is possible. As for a time period I can pretty much give you a shut off date of no later than 1750ish. Its construction and location lead me to believe that it is much earlier than 1750s. The earlist trade axes date into the mid/late 1500s. it is pretty hard to nail these down to a smaller date range.
