A positive organ (‘organetto‘) presented to the Kangxi emperor by Teodorico Pedrini on on 24 August 1712 “in the midst of all these difficulties” (i.e., the ‘Rites Controversy’.) (Matteo Ripa, Giornale, ed. Michele Fatica (Naples: Instituto Universitario Orientale di Napoli, 1996) Vol. 2, 85.)
It is possible that PEK1712b was merely a rebuilding by Pedrini and his craftsmen of PEK1712a.
