The N&S Reflex was designed and patented by Arthur Newman. The usual lens is a Zeiss or Ross-Zeiss Tessar, a Ross Xpres was introduced in 1913. A telephoto, at first a Bis-Telar, was interchangeable with the standard lens, the Telecentric was added in 1913. The 5" x 4" model remained available (probably existing stock) for a year or so after the start of World War I, sales then ceased and did not resume after the war. Total production probably amounted to fewer than 200 cameras. The camera was available in 9 x 12 cm as well as the quarter-plate and 5" x 4" models. The price of a quarter-plate was 23.10.0.
