That's great--but these are customer tapes, not mine and many are from the 1960s and 70s. (About 2/3s of the current batch are 7-track) Perhaps 50 years of storage takes its toll. I don't know. The other minor annoyance is that 40-50 years tends to dry out the adhesive on labels and less often, leader splices. As far as racks go, you can sometimes find the 16mm film racks at auction--they rarely attract bids. They're mostly Neumade products. --Chuck
