[GreenKeys] Durability

[Jeffrey D Angus]

I acquired my first Model 15 back in 1972 or so, and I was amazed by
the date stamp on the machine. MPF 1944.
"Wow, it's 28 years old." And I never had to do anything except add
paper.
Around 1985, I acquire a model 19 table set. An even older date code.
Putting the at machine at about 45 years old. All I had to do with that
one was add paper and tape.
I was convinced, these machines would out live us all.
Now, they're 70-75 years old. And except from the ravages of neglect,
it looks like my prediction may be correct.

What truly impresses me is the thought that went into the design of
things back in the '30s and '40s.
