Jim You are showing you lack of experience in tuning Square Grands as many of them have oblong tuing pins. Basically they are flat on two sides and round on the other two. Instead of a square top that is tapered you see an flat sided oval when viewed from the top. Some harpsichord makers still employ oblong pins on their instruments.
