Hi,
I have a Victor Electrola RE-57 that's missing the mic, horseshoe-shaped weight that fits on the reproducer, and the needle cup for used needles. Heck, I'm missing one of the wood knobs too. The following link is of the items from Radiola Guy's web site. Is shows the mic, weight, the needle cup on the left (in bronze), and the knob.
