Although beeing quite popular camera in the past, it's not easy to find bakelite Yunkor in good condition. At least 4 colour-related versions can be found nowadays:
1. Totally black one (most common);
2. Black body, but internal lens screw in brown colour (source: Fotoua.com);
3. Black body, but external viewfinder in brown colour (see camera opposite) Camera opposite from Ilya Stolyar (USA) coll. ;
4. Browny-red body, but both external viewfinder and internal lens screw in black colour. Ultra rare to find (source: Mirfoto).
