Is anyone living who installed a wood pin arm?

I understand why there is 5 wire? But I would love to know when the last wood pin arm went up. And why in the year 2013, we are installing filler glass? If a wood pin arm is over 60 or 70 years old, I would be embarrassed to have a wood pin arm. I was 7 years in the trade when I came across my first one. And I have been working on systems where 30% are all wood pin arms. I figure its got to be World War II, because they didnt have steel. Reppy do you know? If thats true, wood pin arms have to be 70 years old.
