I have an Hulot Harmel that looks the same (minus the sidewing) as the one in the link you sent. And I actually got this curious other one with the similar placement of the sidewing, from Emerald. The rounded sidewing, though, on mine has a distinct bevel on it and any unlike the french one in Emerald's collection, mine is not "rhino" style, but rather flat. I'm going to compare it a little closer, though. I personally don't care about the maker's name on the anvil, but some people have offered me more cash for it, if it is proved to be a Söderfors. And I would be tempted to part with it.
