All I've read on the conservation threads seems to indicate that the only protection against degradation is refrigeration under low temperatures. It seems that there are unstable bonds in many plastics that come undone with time. It's an ugly problem--and I suspect the only solution is to replicate the parts. Heaven knows, I've had terrible experiences with PVC and ABS. I'm staring at a 9-track streamer drive that's decomposing on its own in the dark. Problem is that not only the panel parts are made from plastic, but so is the main chassis. This fals warld is bot transitory -- Dunbar --Chuck
