Panorama Camera 24 x 93 mm and Slide Projector "Panorama-90", 20

Graumann, Germany. A set of prototypes: 1) Panorama camera 24 x 93 mm for 135 film. A Fed stereo camera was adapted and a housing was made. With Mamiya-Sekor 6.3/65 mm, glass clean, in Seikosha-S B 1–1/500 sec., works. Helical focusing up to 0.5 m. For film transport, it must be transported three times. The lens was measured and adjusted under the collimator. (3/3) – And: 2) "Panorama-90" slide projector, for slides of 24 x 93 mm or smaller. Made entirely of metal and completely manually. With 3 condenser lenses (2 x Ø 110 mm, 1 x Ø 80 mm), mirror and heat protection filter, as well as two powerful fans with air baffles for cooling the slide and the lenses. The device is operated with 24 volt/250 watt halogen lamps using a 24 volt/300 watt power supply unit. Projection lens is a Mamiya-Sekor 3.5/100 mm. With a screen distance of approx. 3–4 meters, there is a projection image approx. 3 meters wide. Suitable for continuous operation. (2/3) – In addition: Three different, modified slide frames as samples, 2 from RBT-Stereo, 1 from Mamiya. – A favorite project by Graumann, because the existing 6 x 7 cm quality projectors do not illuminate the 24 x 93 mm format. A unique opportunity to acquire a solid and modern panoramic projector in full working condition.

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)
