The best insulators are in the front, with the riff raff in the back along with some pop bottles: U-17 NN Pittsburgh, 2 CD 106 Lynchburgs, A CD 133 Brookie, and a CD 125 WU 5A. Also in the back is the Kellogg wall phone. It needs the bells, terminal board on top, the bottom wood shelf, and the crank mech.I'll either try and fix it up (if i can find the parts) or use it as part of a trade for a better one.
