Beautiful sword indeed, Dana 
I am surprised with one detail ... which links to another. 
Its weight is rather significant; 55% heavier than mine. Which is quite impressive, given that the overall dimensions of both are equivalent. Even your blade doesn't appear to be thicker than mine, although of a different profile. On the other hand the point of balance of yours is rather close from the guard; mine is almost 3 1/2" from the cup bottom. 
We then may conclude that the cup of your sword is 'extremely' heavy, right ? 
Maybe due to the bowl being made with (much) thicker iron plate, together with the weight of the multiple adornments ? 
Can you check the blade ricasso inside the bowl and see if it is adorned ...something like mine, which has a brass decorated 'ferrule' ? This could indicate further familiarity in the smith style, due to being an uncommon procedure.
