|Location||Beijing, Xitang (West Church, Our Lady of Seven Sorrows)|
|Builder||Alexandre Provost, C.M.|
An organ reported by Vincentian historian Octave Ferreux in 1963. He claimed that Alexandre-Jean Provost C.M. (1850-97) built an organ for the Xitang, itself rebuilt in 1867. But Provost only arrived in Beijing in 1872; so if this is true, then this putative organ in the Xitang (PEK1872) must have been constructed around or perhaps sometime after that date.
