It isn't the hitches, but more likely the long open back scale. These aren't tuned, because it's not possible, and because there's no direct relationship between the rear duplex and the speaking length anyway, like there is between the speaking length and the front duplex. String energy doesn't pass across a bridge like it does with the string rocking across a V-bar in front, causing the too long front duplex to squall obnoxiously. Any note you strike anywhere in the scale will find a sympathetic at some partial in some back segment, and that segment will sound. Tuned rear duplexes are typically too short to make much supportive sound at all, so these long segments are louder than you hear in other pianos, including the pre vertical hitch Baldwins. Some people don't mind the noise, and some hate it. Harold apparently didn't mind it. Ron N
