I'm chasing the head piece for a Mitutoyo Holtest 6 to 8mm. I have the micrometer part, but the head part with the 3 prongs is damaged. This is an old unit and spares are no longer available for it. Someone has managed to break off one of the 3 M0.6x.125 screws in a tapped hole, so even if I could get parts, fitting them could be difficult.
