Ok, I mis-spoke. I know from experience that holes did not align accurately, but were close enough. It turns out that each section or piece was done a little differently. The side members were done pretty much as I described but the steering holes were done much later and reamed for accurate alignment. This is VERY early information so procedures may have changed at a later date. Below is a snippet from a 1928 American Machinist article.
