This is a basic derailleur, probably made in China by Xundah. I say this because the rear parallelogram plate if stamped 'SYPO'. One of the several names that the manufacturer of Xundah derailleurs uses is Ningbo Sypo Industry Co., Ltd..

This fine object is branded as 'Sunstar' by its, possibly Brazilian, importer. It is included here because of my obsession with derailleurs named after our nearest star.
