@RosinedUp: Yes, it is actually pretty similar to some styles of modern electric.  I'd say you're right and a piezo pickup would be all it would take to have it functional as one.

@Mad_Wed: Not knowing what wood the "body" is made from, it's hard to speculate how much it might weight.  But yeah, it does look like it's probably rather heavy for a violin.  That may have been intentional, though.  So the player could practice on something quiet and heavy, and then when they switched over to their acoustic it would feel like it weighed almost nothing.  Kind of like how some runners wear or carry extra weights when training to build up their strength and endurance more.
