灰色的IIIc型相机，编号387827，带卡尔蔡司耶拿产Tessar f4.5/135mm镜头（编号667933），带联动测距仪螺纹卡口，同样为灰色。本拍品的漆水和对焦接环与灰色徕兹Hektor f4.5/135mm镜头非常相似。由于制作精良的对焦接环和精确的三脚架接口，我们认为，它可能曾被用作环摄相机，正如在James Lager著作第一卷91页上描述的W.H. RBK2一样。带二战时期生产的里拉琴形状的VIOOH通用取景器。 Grey painted IIIc no.387827 with unknown Carl Zeiss Jena Tessar 4.5/13.5cm no.667933 in rangefinder coupled screw mount in grey paint. The paint and the focusing mount is very similar to the grey Leitz Hektor 4.5/13.5cm. Due to the well made focusing mount with the exact tripod mount we do believe that it could have been used as a Rundbildkamera outfit like the W.H. RBK2 illustrated in James Lager Vol. I page 91. With a war-time lyre-shaped VIOOH universal finder.
