Looks, although pinch wheel is not soft or hard, the surface has gone
micro-crazed. As much bigger than C90 type cassette player pinch wheels,
will try a piece of silicone rubber tube stretched over the original. A
sensible use for a selfie-stick, using the silicone grip removed from
the handle.
Motor is dated 1979 but perhaps a replacement and the m/c is earlier,
the pcb looks typical late 1960s
