Jim,
William Flynn used long tees, some upwards of 90-100 yards long, pretty early on in the 1920s, usually, but not always, in place of multiple tees. Thus it is no surprise that one of his construction foremen, Red Lawrence, would use them later on as well. I think I posted a few months back a number of courses where Flynn used them and the dates of construction. I'll try to get some info for you tomorrow.
