On this side of the pond, '20s/'30s WurliTzer had bifurcated tuning pins but the wedge was/is very accessible from below the pinblock. They also have locking nuts to keep the wedges tight and in place. The rest of the piano may be toast, but, by golly, them pins are tight! Conrad Hoffsommer, RPT, MPT, CCT, PFP, ACS, CRS.
