360-Degree Panoramic Camera, c. 1900

Martinus Pedersen, Hadsund, Denmark. Mahogany housing with a lower, removable spring-driven motor, running, for 112 rollfilm, 177.8 mm wide (on the market since 1898), exposure setting via a variable slit width from 17 mm to 0, also adjustable diagonally for exposure compensation in overly bright skies (wider at the top, narrower at the bottom), the longitudinal rollers to the left and right of the slit both widen in the middle (from 6.4 to 8 mm in diameter), an auxiliary slide protrudes from the side of the housing, which must be pulled out to open the slit. According to the inscription on the film drum (with film reel remnants from shots of this period), it was designed for a 24.6 cm lens, fitted with a Rodenstock Eurynar 6.8/24 cm no. 20015 from 1909, iris diaphragm up to f/44. Dimensions with motor (with crank): 35 x 28 x 36 cm. – Note: The lens board for this lens is of a different date, therefore the camera could be several years earlier, at the earliest from 1898 onwards, and thus designed and tested before other known panoramic cameras. This is the only known example of this camera.

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)
