  municipality thereof operating on a sound actuarial basis and subject to
  the supervision of the insurance department of  this  state  in  a  plan
  which  provides  service  retirement benefits equal or superior to those
  provided under this section and at  the  date  of  his  retirement  such
  member  would  have been eligible for such benefits had he not separated
