Attached are two photos of a Sohmer Grand bridge with bridge agraffes. Very interesting in that the string bears on the top of the aggraffe hole, not on the bottom as one might expect. In order to maintain positive downbearing on the bridge, the bridge has a raised shelf behind the aggraffe such that the string runs uphill to the bridge from the hitch pin area before running downhill to the aggraffe from the short span off the front of the shelf. The slope of the string then rises as you move toward the tuning pin termination side. Sadly, I did not have my bubble gauge to try and determine the net bearing and it's definitely got me reaching for the fish oil capsules thinking about whether a measurement of the relationship between the hitch segment and the front segment would reveal the net bearing anyway. The piano sounded like caca, btw, but there were other issues. In spite of that, the tone was surprisingly focused.
