<HTML>Hello Gordon !     The Apollo piano factory was began by Melville Clark in 1901. The factory was in DeKalb Ill.  This Co. was bought by Wurlitzer at some time in the Twenty's.     The Apollo was a much better built piano than the Wurlitzer.  The   It was mostly built to be used as a Grand  piano for the Apollo Player system. But many were sold as a straight pianos.        The scale  M.C-3  a  5ft.3in. was by far their their most popular piano.  The bass had 13 single and 13 doubles.  They used the " Seaverns "  action. Most used the soft  pedal to  lift the hammer rail and did not shift the action.  It also used a lost motion eliminator.        It is a well built Piano  if  it is a  real Apollo. Wurlitzer  put this name of some Wurlitzer built grands that used the "Thayer" actions. The "Thayer" actions were much cheaper  and so was the Wurlitzer  piano..     There are some 5ft. 3in. pianos that are higher performing in sound than the Apollo but not that many.  It,s a good piano.   Hope this helps,   Jack Wyatt</HTML>
