The tuners on this guitar appear to be "hydrant" tuners as used on the Senator model, but with the mounting plates cropped in order to fit on the headstock. No 103 was almost certainly the third V3 solid ever made by Hofner. At that stage they were no doubt still experimenting with ideas on how best to construct and fit out such a radical (for Hofner) model. Shortly afterwards, special tuners had been sourced for the V3 which were never used before or since on any other model.
