In the late 1890's to early Edwardian era this was standard practice on some Broadwood Grands - to have but one bridge pin per string at the bottom end of the scale. I have found this in double-overstrung Grands by Broadwood in the tenor break. Sometimes they went even further and used much larger diameter bridge pins for the Bass end and the string covering was encased in a cloth sleeve as it went over the bridge. Broadwood even went so far as giving the top 8ve. four metals per note - and they are quite difficult to tune in application.
