After reviewing Bowers, I was unable to determine where in Regina
production the stained-glass, bowed-front, coin-op changer series
started and ended.  Specifically I am referring to serial no. 50561,
which supposedly shipped July 1900.

  [ From the fact that you already know when Regina #50561 was shipped,
  [ I assume that you have gotten what information you can from Bob
  [ Yates (rsublima@juno.com.geentroep; delete .geentroep), the keeper
  [ of the original Regina factory records for the MBSI?
