I'm wondering what the normal time frame is on this? Pre-mature would indicate more care should be taken in storage, i presume? According to the ser#, this is a 96, 21 years old. Too soon? The storage (playing) room isn't kept at a constant temp; i turn up the heat when i'll be there for a while but otherwise, heat turned down and chilly but certainly not freezing (which is what i've heard will speed up checking). Anyone familiar with the process?
