Thanks Ed, I guess it would be between 81and '87? Do the serial numbers matter? Would like to figure out those. When did Chief Cook arrive?
They are good performers and the mechanics are nice. Like a lot of older binoculars, they have fungus, quite a bit on the right side but I'm not sure fungus hurts resolution really, and it's not picking up flare too much. Tempted to clean them but they still work fine.
"Chief" Cook is my affectionate reference to WJC, who was a chief US Navy optical repairman. He said (post #6) he starting working with Aerolites in 1987, which defines t=0 in his memory bank.
As to serial numbers, the database Renze de Vries and I have suggests that they don't contain a date code. This is most likely because they were not made by Hiyoshi Kogagu. In fact, there may have been several Aerolite manufacturers over the years.
I send all my binoculars to Nicolas Crista (NRC Optics) for cleaning and alignment. Most older items need it, even if they stood in a box for 30 yrs.
Thanks
Ed
