Contax D, X-Ray-Tenax, and "Metax" Prototype

Zeiss Ikon, Dresden. 1) X-Ray-Tenax no. W.13776, back no. W.13946, for 24 x 24 mm format; rewind lever missing (can be replaced). (3/3) – 2) X-Ray-Tenax no. W.34887, different design, with original body cap. (3–4/3) – 3) A variant based on the Zeiss Ikon X-Ray-Tenax (24 x 24 mm) but featuring a viewfinder; we call it "Metax" after its shutter (a name sounding much like "Tenax"). Shutter speeds: B, 1–1/400 sec.; Ludwig-Dresden Victar 2.9/5 cm with front-element focusing; functional; back no. W.33555. Likely a prototype of a Tenax-style camera created by a Zeiss Ikon employee during the early post-war period, when cameras were extremely expensive. (3/3) – And: 5–6) Zeiss Ikon Contax (with viewfinder magnifier) ??and Zeiss Ikon VEB Contax D, both with Biotar 2/58 mm lens; both shutters require manual assistance to operate. (3/3-)

布雷克拍品等级是为了方便竞买人判断拍卖品的成色而设置的。布雷克等级用1到6级来标注外观和功能的成色，(从非常好到非常差)。 在目录图册里用括号里的2个数字来表示，前一个数字表示外观成色的级别，后一个数字表示功能成色的级别。如(3/2)表示外观成色是3(满意的)，功能成色2(好)。 成色 定义参照下列标准： 1 - 非常好 (未使用过，没有使用痕迹) 2 - 好 (新，极少的使用痕迹) 3 - 满意的 (普通的使用痕迹) 4 - 及格的 (明显的使用痕迹，某个非主要部件是后配的) 5 - 有缺陷的 (极明显的使用痕迹, 某个主要部件是后配的，功能上有缺陷，需要修理) 6 - 非常差 (严重破损, 缺少重要部件)
