I have had the same experience as Richard with some old Brovira.  I have some bought in February 1971, stored in temperate room conditions and is still free of fog.  If it has lost some contrast then I'm not aware of it.  In those days my contrast control and record keeping were not good.

The Record-Rapid from those days has not fared well.  ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
