I would like to know who this is, where they are from, and time period.
I've come up with four different smiths, none of which I can find any useful information on.
J. Pettersen - thought to be from Norway or New Zealand
Johan Pettersen - of Sweden around 1760
Julius Pettersen - of Norway from 1859 - 1930
Jacob Pettersen - of Norway around 1700
