The sword that MRJ was holding in “The Miller’s Daughter” could have been from Hook’s ship, but then how did it get back to Hook’s ship? I thought it was just a sword that was laying around in Mr. Gold’s shop.
It might even be a different sword from the pic Ginny tweeted of J-Mo in character in NL. To me, the blades look different. The only commonality might be the curvature of the blade. But it makes more sense that they’re two different swords: the first one Neal is holding is from Mr. Gold’s shop (where it remains to this day), and the second sword is from Hook’s ship.
But I still don’t think either sword is the object Emma is holding in the newest pic from S3. To me, it looks mostly like a gun or at best a dagger, but not a sword with an elongated blade (even taking into account angle difference).
