Does look like a pretty long stem on there, probably for 6'2" or 6'4". As
@bigjim said, there was a myriad selection of stems back then, with different stem lengths and heights.
Wish I could find the old flyer showing all that were available, but probably still hanging in the garage at my Fathers old house, sold 20 years ago. I rode an old Schwinn with Columbus Tubing on a lot of rides like that, performance was good and it handled the miles quite well until the frame got too old and noodly for me.
