This organ was built by G. S. Caspari in 1734. Both DIGNATH & ZIESMANN 1987: 191 and BACHTIN & DOLIESEN 1998: 167 attribute this organ erroneously to Casparini. As the building year of this organ is established at 1734-1735, it cannot have been built by Casparini. RENKEWITZ & JANCA (1984: 46 note 48) indeed attribute the organ to Georg Sigismund Caspari.
Probably, it had around 12 stops and 1 manual and pedal. On the picture a console of the romantic era is visible, no doubt the result of a thorough rebuilding by Terletzki, Goebel or Sauer.
I have no further information about this instrument, other than that as the church lies in Russian territory now, the organ would not stand any chance of surviving. Although the church was undamaged (only the tower had some damages) by 1945, it turned gradually into ruins in the years afterwards (DEHIO 1993: 608), as is the case with most of the churches in the Russian part of East-Prussia.
