does this info help at all? thanks!
It'not the earliest model then, likely a transitional model, still old, still valuable, still nice.
According to this timeline:

That puts the stem post-1972. So I would say this is from around that time. I would have guessed it is earlier but I think it is unlikely that bolt bolts were changed but it is possible.
