On my way to The Rohde show today stopped by the Antique Trove in Roseville CA and found a number of common insulators. In one case was this beautiful CD 317Chambers in Lt. Green. Looked very close to mint without asking them to take it out of the case. The $1400 price tag was a little rich for me. But thought I would let others know what I found and left. See you at the show!
