On the 12" Boba's built back in the late 70's was their quite a gap between the hands and the ends of the arms? Also, it looks like the hands just plug into the arm's ends so these could spin around?? I recently bought one and it looks like someone used white caulk to put between the hands and arms, it does not look like they were gluing them back together just like they did not like the gap....? Anyone taken the hands/arms apart?
